SOA驱动电路
电路设计报告
（姓名：_________学号：________）
SOA驱动电路
一、设计要求
半导体光放大器(SOA)是一种不需要经过光／电／光的变换，就可以直接放大微弱光信号的光放大器，所以SOA驱动电路，主要是给SOA提供驱动电流，SOA的注入电路一般取50-150mA。
.驱动电路设计的主要思想就是提供稳定的驱动电路保证SOA正常工作。
二、原理框图及设计原理说明
设计原理：SOA驱动电流一般取几十到几百毫安，由于SOA需要的驱动电流较小而且需要要求比较稳定，没有直接的能够提供毫安级的供电装置，因此我们需要设计一个驱动电流，主要原理就是先利用一个电压基准精确的给精密放大器提供一个输入电压，电压经过精密放大器放大后接个跨阻加在三极管上，三极管有放大电流作用，放大后就可以作为SOA的驱动电流。
SOA

When the supply voltage is at its maximum and I L is at its minimum, R S should be large enough so that the current flowing through the LM4040 is less than 15 mA.R S is determined by the supply voltage, (V S ), the load and operating current, (I L and I R ), and the LM4040’s reverse breakdown voltage, V R .Printed circuit board layout considerationsLM4040s in the SOT23 package have the die attached to pin 1, which results in an electrical contact between pin 2 and pin 3. Therefore, pin 1 of the SOT-23 package must be left floating or connected to pin 2.LM4040s in the SC75 package have the die attached to pin 2, which results in an electrical contact between pin 2 and pin 1. Therefore, pin 2 must be left floating or connected to pin1.RL R S S I I V V R +−=Issue 4 - July 200811 © Diodes Incorporated 2008Package outline - SOT23Note: Controlling dimensions are in millimeters.

LED显示屏参数
LED显示屏参数LED显示屏参数与术语：1、LED亮度发光二极管的亮度一般用发光强度(Luminous Intensity)表示,单位是坎德拉cd；1000ucd（微坎德拉）=1 mcd（毫坎德拉）, 1000mcd=1 cd。
室内用单只LED的光强一般为500ucd-50 mcd，而户外用单只LED 的光强一般应为100 mcd-1000 mcd，甚至1000 mcd以上。
2、 LED象素模块LED排列成矩阵或笔段，预制成标准大小的模块。
室内显示屏常用的有8*8象素模块、8字7段数码模块。
户外显示屏象素模块有4*4、8*8、8*16象素等规格。
户外显示屏用的象素模块因为其每一象素由两只以上LED管束组成，固又称其为集管束模块。
3、象素(Pixel)与象素直径LED显示屏中每一个可被单独控制的LED发光单元(点)称为象素(或象元)。
象素直径∮是指每一象素的直径，单位是毫米。
对于室内显示屏，一般一个为单个LED，外形为圆形。
室内显示屏象素直径校常见的有∮3.0、∮3.75、∮5.0、∮8.0等，其中以∮3.75和∮5.0最多。
在户外环境，为提高亮度，增加视距，一个象素含有两只以上集束LED；由于两只以上集束LED一般不为圆形，固户外显示屏象素直径一般用两两象素平均间距表示：□10、□11.5、□16、□22、□25。
4、点间距、象素密度与信息容量LED 显示屏的两两象素的中心距或点间距(Dot Pitch)；单位面积内象素的数量称为象素密度；单位面积内所含显示内容的数量称为信息容量。
这三者本质是描述同一概念：点间距是从两两象素间的距离来反映象素密度，点间距和象素密度是显示屏的物理属性；信息容量则是象素密度的信息承载能力的数量单位。
点间距越小，象素密度越高，信息容量越多，适合观看的距离越近。
点间距越大，象素密度越低，信息容量越少，适合观看的距离越远。
5、分辨率LED显示屏象素的行列数称为LED显示屏的分辨率。
LM4040
LM4040December 9, 2010 Precision Micropower Shunt Voltage ReferenceGeneral DescriptionIdeal for space critical applications, the LM4040 precision voltage reference is available in the sub-miniature SC70 and SOT-23 surface-mount package. The LM4040's advanced design eliminates the need for an external stabilizing capac-itor while ensuring stability with any capacitive load, thus making the LM4040 easy to use. Further reducing design ef-fort is the availability of several fixed reverse breakdown voltages: 2.048V, 2.500V, 3.000V, 4.096V, 5.000V, 8.192V, and 10.000V. The minimum operating current increases from 60 μA for the LM4040-2.5 to 100 μA for the LM4040-10.0. All versions have a maximum operating current of 15 mA.The LM4040 utilizes fuse and zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1% (A grade) at 25°C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating tempera-tures and currents.Also available is the LM4041 with two reverse breakdown voltage versions: adjustable and 1.2V.

EquipmentThe LM4040series of shunt voltage references are versatile,easy-to-use references that cater to a vast array of applications.The2-pin fixed-output device requires no external capacitors for operation and is stable with all capacitive loads.Additionally,the reference offers low dynamic impedance,low noise,and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures.The LM4040uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances,ranging from0.1%(max)for the A grade to1%(max)for the D grade.Thus,a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications.Packaged in space-saving SC-70and SOT-23-3packages and requiring a minimum current of45µA(typ),the LM4040also is ideal for portable applications.The LM4040xI is characterized for operation over an ambient temperature range of–40°C to85°C.The LM4040xQ is characterized for operation over an ambient temperature range of–40°C to125°C.Please be aware that an important notice concerning availability,standard warranty,and use in

SupplyLM4040PRECISION MICROPOWER SHUNT VOLTAGE REFERENCESLOS456J–JANUARY 2005–REVISED SEPTEMBER 2006Figure 7.Test CircuitThe LM4040does not require an output capacitor across cathode and anode for stability.However,if an output bypass capacitor is desired,the LM4040is designed to be stable with all capacitive loads.There is a parasitic Schottky diode connected between pins 2and 3of the SOT-23packaged device.Thus,pin 3of the SOT-23package must be left floating or connected to pin 2.The LM4040x-41is designed to be a cost-effective voltage reference as required in 12-bit data-acquisition systems.For 12-bit systems operating from 5-V supplies such as the ADS7842(see Figure 8),the LM4040x-41(4.096V)permits operation with an LSB of 1mV.Figure 8.Data-Acquisition Circuit

INFORMATION(continued)In a typical shunt-regulator configuration(see Figure9),an external resistor,R S,is connected between the supply and the cathode of the LM4040.R S must be set properly,as it sets the total current available to supply the load(I L)and bias the LM4040(I Z).In all cases,I Z must stay within a specified range for proper operation of the reference.Taking into consideration one extreme in the variation of the load and supply voltage(maximum I L and minimum V S),R S must be small enough to supply the minimum I Z required for operation of the regulator,as given by data-sheet parameters.At the other extreme,maximum V S and minimum I L,R S must be large enough to limit I Z to less than its maximum-rated value of15mA.R S is calculated according to Equation1:Figure9.Shunt

Operating Ratings indicate conditions for which thedevice is functional, but do not guarantee specific performance limits. For guaranteed specification and test conditions, see the ElectricalCharacteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.Note 2.The maximum power dissipation must be derated at elevated temperatures and is dictated by T JMAX (maximum junction temperature), θJA (junction to ambient thermal resistance), and T A (ambient temperature). The maximum allowable power dissipation at any temperature is PD MAX = (T JMAX – T A )/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040 and LM4041,T JMAX = 125°C, and the typical thermal resistance (θJA ), when board mounted, is 326°C/W for the SOT-23 package.Note 3.The human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each pin.Note 4.Typicals are at T J = 25°C and represent most likely parametric norm.Note 5.Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation using Statistical Quality Control (SQL)methods.Note 6.The boldface (over temperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage Tolerance ±[(∆V R /∆T)(65°C)(V R )]. ∆V R /∆T is the V R temperature coefficient, 65°C is the temperature range from –40°C to the reference point of 25°C, and V R is the reverse breakdown voltage. The total over temperature tolerance for the different grades follows:A-grade: ±0.75% = ±0.1% ±100ppm/°C × 65°C B-grade: ±0.85% = ±0.2% ±100ppm/°C × 65°C C-grade: ±1.15% = ±0.5% ±100ppm/°C × 65°C D-grade: ±1.98% = ±1.0% ±150ppm/°C × 65°CExample: The A-grade LM4040-2.5 has an over temperature Reverse Breakdown Voltage tolerance of ±2.5 × 0.75% = ±19mV.Note 7.When V OUT ≤ 1.6V, the LM4041-ADJ must operate at reduced I R . This is caused by the series resistance of the die attach between the die (–)output and the package (–) output pin. See the Output Saturation curve in the Typical Performance Characteristics section.Note 8.Reference voltage and temperature coefficient will change with output voltage. See Typical Performance Characteristics curves.LM4040 and LM4041 Electrical Characteristic NotesLM4041 Typical CharacteristicsLM4041 Typical Characteristics* Output Impedance vs. Freq.Test Circuit‡ Large Signal ResponseTest Circuit† Reverse CharacteristicsTest CircuitApplications InformationThe LM4040 and LM4041 have been designed for stableoperation without the need of an external capacitor con-nected between the (+) and (–) pins. If a bypass capacitor is used, the references remain stable.Schottky DiodeLM4040-x.x and LM4041-1.2 in the SOT-23 package have a parasitic Schottky diode between pin 2 (–) and pin 3 (die attach interface connect). Pin 3 of the SOT-23 package must float or be connected to pin 1. LM4041-ADJs use pin 3 as the (–) output.Conventional Shunt RegulatorIn a conventional shunt regulator application (see Figure 1),an external series resistor (R S ) is connected between the supply voltage and the LM4040-x.x or LM4041-1.2 reference.R S determines the current that flows through the load (I L ) and the reference (I Q ). Since load current and supply voltage may vary, R S should be small enough to supply at least the minimum acceptable I Q to the reference even when the supply voltage is at its minimum and the load current is at its maximum value. When the supply voltage is at its maximum and I L is at its minimum, R S should be large enough so that the current flowing through the LM4040-x.x is less than 15mA, and the current flowing through the LM4041-1.2 or LM4041-ADJ is less than 12mA.R S is determined by the supply voltage (V S ), the load and operating current, (I L and I Q ), and the reference ’s reverse breakdown voltage (V R ).R s = (V s – V R ) / (I L + I Q )Adjustable RegulatorThe LM4041-ADJ ’s output voltage can be adjusted to any value in the range of 1.24V through 10V. It is a function of the internal reference voltage (V REF ) and the ratio of the external feedback resistors as shown in Figure 2. The output is found using the equation (1)V O = V REF ´ [ (R2/R1) + 1 ]where V O is the desired output voltage. The actual value of the internal V REF is a function of V O . The “corrected ” V REF is determined by (2)V REF ´ = V O (∆V REF / ∆V O ) + V Ywhere V O is the desired output voltage. ∆V REF / ∆V O is found in the Electrical Characteristics and is typically –1.3mV/V and V Y is equal to 1.233V. Replace the value of V REF ´ in equation (1) with the value found using equation (2).Note that actual output voltage can deviate from that pre-dicted using the typical ∆V REF / ∆V O in equation (2); for C-grade parts, the worst-case ∆V REF / ∆V O is –2.5mV/V and V Y = 1.248V.The following example shows the difference in output voltage resulting from the typical and worst case values of ∆V REF / ∆V O :Let V O = +9V. Using the typical values of ∆V REF /∆V O , V REF is 1.223V. Choosing a value of R1 = 10k Ω, R2 = 63.272k Ω.Using the worst case ∆V REF / ∆V O for the C-grade and D-grade parts, the output voltage is actually 8.965V and 8.946V respectively. This results in possible errors as large as 0.39%for the C-grade parts and 0.59% for the D-grade parts. Once again, resistor values found using the typical value of ∆V REF / ∆V O will work in most cases, requiring no further adjustment.Figure 4. Voltage Level DetectorR1120kR21MR1120k R21M12V Figure 3.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specification and test conditions, see the ElectricalCharacteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.Note 2.The maximum power dissipation must be derated at elevated temperatures and is dictated by T JMAX (maximum junction temperature), θJA (junction to ambient thermal resistance), and T A (ambient temperature). The maximum allowable power dissipation at any temperature is PD MAX = (T JMAX – T A )/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040 and LM4041,T JMAX = 125°C, and the typical thermal resistance (θJA ), when board mounted, is 326°C/W for the SOT-23 package.Note 3.The human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each pin.Note 4.Typicals are at T J = 25°C and represent most likely parametric norm.Note 5.Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation using Statistical Quality Control (SQL)methods.Note 6.The boldface (over temperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage Tolerance ±[(∆V R /∆T)(65°C)(V R )]. ∆V R /∆T is the V R temperature coefficient, 65°C is the temperature range from –40°C to the reference point of 25°C, and V R is the reverse breakdown voltage. The total over temperature tolerance for the different grades follows:A-grade: ±0.75% = ±0.1% ±100ppm/°C × 65°C B-grade: ±0.85% = ±0.2% ±100ppm/°C × 65°C C-grade: ±1.15% = ±0.5% ±100ppm/°C × 65°C D-grade: ±1.98% = ±1.0% ±150ppm/°C × 65°CExample: The A-grade LM4040-2.5 has an over temperature Reverse Breakdown Voltage tolerance of ±2.5 × 0.75% = ±19mV.Note 7.When V OUT ≤ 1.6V, the LM4041-ADJ must operate at reduced I R . This is caused by the series resistance of the die attach between the die (–)output and the package (–) output pin. See the Output Saturation curve in the Typical Performance Characteristics section.Note 8.Reference voltage and temperature coefficient will change with output voltage. See Typical Performance Characteristics curves.LM4040 and LM4041 Electrical Characteristic NotesLM4041 Typical CharacteristicsLM4041 Typical Characteristics* Output Impedance vs. Freq.Test Circuit‡ Large Signal ResponseTest Circuit† Reverse CharacteristicsTest CircuitApplications InformationThe LM4040 and LM4041 have been designed for stable operation without the need of an external capacitor con-nected between the (+) and (–) pins. If a bypass capacitor is used, the references remain stable.Schottky DiodeLM4040-x.x and LM4041-1.2 in the SOT-23 package have a parasitic Schottky diode between pin 2 (–) and pin 3 (die attach interface connect). Pin 3 of the SOT-23 package must float or be connected to pin 1. LM4041-ADJs use pin 3 as the (–) output.Conventional Shunt RegulatorIn a conventional shunt regulator application (see Figure 1),an external series resistor (R S ) is connected between the supply voltage and the LM4040-x.x or LM4041-1.2 reference.R S determines the current that flows through the load (I L ) and the reference (I Q ). Since load current and supply voltage may vary, R S should be small enough to supply at least the minimum acceptable I Q to the reference even when the supply voltage is at its minimum and the load current is at its maximum value. When the supply voltage is at its maximum and I L is at its minimum, R S should be large enough so that the current flowing through the LM4040-x.x is less than 15mA, and the current flowing through the LM4041-1.2 or LM4041-ADJ is less than 12mA.R S is determined by the supply voltage (V S ), the load and operating current, (I L and I Q ), and the reference ’s reverse breakdown voltage (V R ).R s = (V s – V R ) / (I L + I Q )Adjustable RegulatorThe LM4041-ADJ ’s output voltage can be adjusted to any value in the range of 1.24V through 10V. It is a function of the internal reference voltage (V REF ) and the ratio of the external feedback resistors as shown in Figure 2. The output is found using the equation (1)V O = V REF ´ [ (R2/R1) + 1 ]where V O is the desired output voltage. The actual value of the internal V REF is a function of V O . The “corrected ” V REF is determined by (2)V REF ´ = V O (∆V REF / ∆V O ) + V Ywhere V O is the desired output voltage. ∆V REF / ∆V O is found in the Electrical Characteristics and is typically –1.3mV/V and V Y is equal to 1.233V. Replace the value of V REF ´ in equation (1) with the value found using equation (2).Note that actual output voltage can deviate from that pre-dicted using the typical ∆V REF / ∆V O in equation (2); for C-grade parts, the worst-case ∆V REF / ∆V O is –2.5mV/V and V Y = 1.248V.The following example shows the difference in output voltage resulting from the typical and worst case values of ∆V REF / ∆V O :Let V O = +9V. Using the typical values of ∆V REF /∆V O , V REF is 1.223V. Choosing a value of R1 = 10k Ω, R2 = 63.272k Ω.Using the worst case ∆V REF / ∆V O for the C-grade and D-grade parts, the output voltage is actually 8.965V and 8.946V respectively. This results in possible errors as large as 0.39%for the C-grade parts and 0.59% for the D-grade parts. Once again, resistor values found using the typical value of ∆V REF / ∆V O will work in most cases, requiring no further adjustment.Figure 4. Voltage Level DetectorR1120kR21MR1120k R21M12V Figure 3.

lm4040电阻计算
问题：如何计算使用LM4040芯片的电阻值？
答案：为了使用LM4040芯片，我们需要计算所需的电阻值。
LM4040是一种精密电压参考源芯片，可用作电压稳定器或比较器中的参考电压。
它的工作原理是通过调整输入电流来产生固定的输出电压。
LM4040芯片有几个版本可供选择，每个版本对应于不同的输出电压。
对于特定版本的芯片，其所需的电阻值可以根据下面的公式计算：
R = (Vref - Vout) / Iadj
其中，R是所需的电阻值，Vref是LM4040的参考电压（通常是2.048V或4.096V），Vout是期望的输出电压，Iadj是芯片的调整电流（通常是60uA）。
举个例子，假设我们希望使用LM4040-2.048芯片来产生一个稳定的2.5V电压。
代入公式，我们可以计算出所需的电阻值：
R = (2.048 - 2.5) / 0.00006 ≈ 8000欧姆
因此，对于这种情况，我们需要选择一个电阻值为8000欧姆的电阻来连接到LM4040芯片。
请注意，由于电阻值的选择有一定的容差和限制，因此在实际设计中可能需要选择最接近的标准电阻值。
此外，如果需要较高的稳定性和精度，还需要考虑温度系数和线性度等因素。

LM4040Precision Micropower Shunt Voltage ReferenceGeneral DescriptionIdeal for space critical applications,the LM4040precision voltage reference is available in the sub-miniature SC70and SOT-23surface-mount package.The LM4040’s advanced design eliminates the need for an external stabilizing capaci-tor while ensuring stability with any capacitive load,thus making the LM4040easy to use.Further reducing design effort is the availability of several fixed reverse breakdown voltages:2.048V,2.500V,3.000V,4.096V,5.000V,8.192V,and 10.000V.The minimum operating current increases from 60µA for the LM4040-2.5to 100µA for the LM4040-10.0.All versions have a maximum operating current of 15mA.The LM4040utilizes fuse and zener-zap reverse breakdown voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ±0.1%(A grade)at 25˚C.Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse break-down voltage accuracy over a wide range of operating tem-peratures and currents.Also available is the LM4041with two reverse breakdown voltage versions:adjustable and 1.2V.Please see the LM4041data sheet.Featuresn Small packages:SOT-23,TO-92and SC70n No output capacitor requiredn Tolerates capacitive loadsn Fixed reverse breakdown voltages of 2.048V,2.500V,3.000V,4.096V,5.000V,8.192V,and
