V3.00GaAs Constant GammaHyperabrupt Tuning VaractorsMA46410 thru 480 SeriesFeaturesq Constant Gamma = 1.0, 1.25 or 1.5q High Q (up to 4000 at -4 Volts)q Larger Capacitance Change with Voltage q More Linear Frequency TuningqHigh and Nearly Constant Modulation SensitivityDescriptionThe MA46450, MA46470 and MA46410 series of tuning varactors are hyperabrupt junction Gallium Arsenide diodes featuring constant gamma 1.0 (MA46450 series),1.25 (MA46470 series) or 1.5 (MA46410 series). These diodes offer high Q (up to 4000) permitting excellent tun-ing performance from VHF through Ka band. Each part in this series exhibits the large change in capacitance versus bias voltage characteristic of hyperabrupt junctions. The standard capacitance tolerance is ±10%, with tighter toler-ances available. Capacitance matching at one or more bias voltages is also available. All diode types are available in a wide selection of ceramic packages and in chip form.ApplicationsThe constant gamma value of 1.0, 1.25 or 1.5 available with these diodes enables the circuit designer to produce significant improvements in circuit performance. Constant gamma tuning varactors permit more linear VCO frequen-cy tuning than do conventional hyperabrupt tuning varac-tors. These varactors are particularly well suited for use in voltage tuned filters, analog phase shifters, and modulatorcircuits.Case Styles30277V3.00* The maximum storage and operating temperature of the plastic1088 case style is 125°C.Absolute Maximum Ratings at +25°CElectrical Specifications at 25°CMA46450 SeriesGamma = 1.0Reverse Voltage 6= 22 Volts minimum Gamma 4= 0.9 - 1.1, V R = 2 - 20 VoltsJunction Capacitance Ratio (C J2/C J20) = 5.0 - 8.0MA46470 SeriesGamma = 1.25Reverse Voltage 6= 22 Volts minimum Gamma 4= 1.13 - 1.38, V R = 2 - 20 VoltsJunction Capacitance Ratio (C J2/C J20) = 8.15 - 12.99Notes:1.All GaAs tuning varactors are available in chip form as well as the case styles shown on the following page.When ordering, specify the desired case by adding the case designation as a suffix to the type number.2.Case parasitics (C p and L s ) are given for most case styles along with case outlines in the appendix.The Cp values listed typically have toler-ances of ±0.02 pF .3.The nominal tolerance at -4 Volts is ±10%.Closer tolerances are avail-able upon request.By adding the suffix A to the part number, a toler-ance of ±5% at -4 Volts is guaranteed.4.The values guaranteed for gamma are measured on unpackaged chips.The total capacitance versus bias voltage curve will deviateslightly from the chip capacitance versus bias voltage curve due to the package parasitic capacitance (Cp).5.Capacitance is measured at 1 MHz.6.Reverse voltage (V B ) is measured at 10 microamps.7.The total capacitance and capacitance ratios shown are for diodes housed in case style 30.Other case styles will result in different val-ues.Total 2, 6, 7Total50 MHz Capacitance Capacitance 7Q at Model Case 1@ -4 Volts Ratio (2/12)-4 Volts Number Style Min./Max.(pF)Min./Max.Typical MA46410300.45-0.60 2.7-4.33000MA46413300.90-1.10 4.2-5.72500MA4641630 1.62-1.98 5.2-4.92500MA4641830 2.42-2.97 5.7-7.61800MA4642030 3.33-4.22 6.0-8.11800MA4642130 4.22-5.17 6.2-8.31200MA4642230 5.04-6.16 6.3-8.41200MA46425309.00-11.006.6-8.81200Environmental Ratings PER MIL-STD-750MIL MethodLevelStorage Temperature 1031See maximum ratingsTemperature Cycle 105110 cycles, -65°C to +175°C Shock 2016500 g’s Vibration 205615 g’s Constant Acceleration 200620,000 g’s Humidity 102110 daysMA46410 Series Gamma = 1.5Breakdown Voltage 6= 18 Volts minimum Gamma 4= 1.4 - 1.6, V R = 2 - 12 VoltsJunction Capacitance Ratio (C J2/C J12) = 6.2 - 10.84V3.00 Case Styles (See appendix for complete dimensions).1100V R(VOLTS).1100V R(VOLTS).1100V R(VOLTS).1100V R(VOLTS).1110100V R(VOLTS)V R(VOLTS).1110100V R(VOLTS)。

A AD5520–11–THEORY OF OPERATIONThe AD5520 is a single channel per pin parametric measurement unit (PPMU) for use in semiconductor automatic test equip-ment. It contains programmable modes to force a pin voltage and measure the corresponding current (FVMI), force current mea-sure voltage (FIMV), force current measure current (FIMI), and force voltage measure voltage (FVMV). The PPMU can force or measure a voltage from –11 V to +11 V. It can force or measure a current over four ranges: 4 µA, 40 µA, 400 µA, and 4 mA. The addition of an external driver allows two extended ranges.The device provides a force sense capability to ensure accuracy at the tester pin. A guard output is also available to drive the shield of a force/sense pair.The AD5520 has an on-board window comparator that pro-vides two bits of useful information, DUT too low or too high.Also provided on the chip is clamp circuitry that will flag via CLHDETECT and CLLDETECT if the voltage applied to FIN or across the DUT has exceeded the voltage applied to CLL and CLH.On chip is clamp circuitry that clamps the output of the force amplifier if the voltage at MEASIOUT and MEASVOUT exceeds CLL and CLH.INTERFACEThe AD5520 PPMU is controlled via a number of digital inputs,which are discussed in detail in the following sections. All inputs are TTL compatible. CS is used to select the device while STB (active low input) latches data available on the other digital inputs and updates any required digital outputs. The rising edge of STB triggers sequence inputs. The remaining digital inputs control the function of the PMU—which measure mode it is in, which com-pensation capacitor is used, and the selected current range.Standby ModeThe AD5520 may be placed into standby mode via the standby logic input. In this mode, the force amplifier is disconnected from the force input (FIN), the switch in series with the force output pins, FOHx, is opened, and the current measure amplifier is dis-connected from the sense resistors. The voltage measure amplifier is still connected across the DUT, so DUT voltage measure-ments may still be made while in standby mode. Figure 3 shows the configuration of the PMU while in standby mode.Table I. Standby ModeSTANDBY FunctionLow Normal Force Mode HighStandby ModeSFigure 3.

The AM0, AM1, and AM2 pins are digital inputs used to establish full-scale current range of the PMU.Table V.

To support other current ranges, these sense resistor values may be changed. A force amplifier can drive a maximum of 6 mA. It is not recommended to increase the maximum current above the nominal range.The two external current ranges use an external buffer to drive the required current. Our example uses 40 mA and 160 mA ranges. These ranges can be changed to suit user requirements for a high current range.Force Control AmplifierThe force control amplifier requires external capacitors connected between the COMPOUTx and COMPINx pins. For stability with large capacitance at the DUT, the largest capacitance value (3000 pF) should be selected. The force control amplifier should always contribute the dominant pole in the control loop. Set-tling times will increase with larger capacitances. ACx inputs select which external compensation capacitor is used.Table VI. AC0, AC1 Compensation Capacitor Selection AC0AC1FunctionLow Low Select External Compensation Capacitor 0 High Low Select External Compensation Capacitor 1 Low High Select External Compensation Capacitor 2 Comparator Function and StrobingThe AD5520 has an on-board window comparator that pro-vides two bits of useful information, DUT too low or too high. CPSEL is the digital input that controls this function, selecting whether it should compare to the voltage sense or the current sense amplifier.Table VII. Comparator Function SelectCPSEL FunctionLow Compare CPL, CPH to MEASVOUTHigh Compare CPL, CPH to MEASIOUTAfter CPSEL has selected which amplifier output is of interest, logic input CPCK is used to initiate comparator sampling andupdate the logic outputs CPOH and CPOL, indicating if thevoltages at MEASIOUT or MEASVOUT have exceeded volt-ages set at CPL or CPH (thus providing DUT too high or DUT too low information). A rising edge on STB is required to clock the CPOH and CPOL data out.Table VIII. CPCK Synchronous Logic OutputsCPOH FunctionLow MEASVOUT or MEASIOUT < CPHHigh MEASVOUT or MEASIOUT > CPHCPOL FunctionLow MEASVOUT or MEASIOUT > CPLHigh MEASVOUT or MEASIOUT < CPL Clamp FunctionClamp circuitry is also included on chip, allowing the output of the force amplifier to be clamped in the event of the voltage atMEASIOUT and MEASVOUT exceeding CLL and CLH. The clamp circuitry play their role in the event of a short or open circuit. When in force current range, the voltage clamps protect the DUT in the event of an open circuit. Likewise, when forcinga voltage and a short circuit occurs, the current clamps willprotect the DUT in this case. The clamps also function to pro-tect the DUT in the event of a transient voltage or current spike that may occur when changing to a different operating mode or when programming the device to a different current range.The digital output flags, which indicate a clamp limit has beenhit, are CLHDETECT for the upper clamp and CLLDETECT output for the lower clamp.Table IX. Clamp Detect OutputsCLHDETECT FunctionLow Upper Clamp InactiveHigh Upper Clamp ActiveCLLDETECT FunctionLow Lower Clamp InactiveHigh Lower Clamp Active High Current RangesWith the use of an external high current amplifier, two highcurrent ranges are possible. The current range values can beselected as required in the application through appropriateselection of the sense resistors connected between MEASI5H,MEASI4H, and MEASIL. When one of these high currentranges (MODE 4 or MODE 5) is selected via the AMx control lines, the appropriate QM4 or QM5 output will be enabled.These outputs can thus be used to control relays connected inseries with the high current amplifier as shown in Figure 8.Table X.

A AD5520–13–CIRCUIT OPERATION Force VoltageMost PMU measurements are performed while in force voltage and measure current modes, for example, when the device is used as a device power supply, or in continuity or leakage testing. In the force voltage mode, the voltage at analog input FIN is mapped directly to the voltage forced at the DUT.When in force voltage and measure current modes, the maxi-mum voltage applied to the input corresponds to the maximum current outputs. Figure 4 shows the transfer function when forcing a voltage.FINFINFigure 4. Voltage Force Transfer FunctionMeasure CurrentFigure 5 shows a simplified diagram of the PMU when in force voltage mode. The control loop consists of the force amplifier with the voltage sense amplifier making up the feedback path.Current flowing through the DUT is measured by sensing the current flowing through a selectable sense resistor, which is in series with the DUT. The current sense amplifier (Gain = 16)generates a voltage at its output, which is proportional to the current flowing through the DUT. This voltage is compared tothe CLL and CLH levels to ensure the clamp voltages have not been exceeded. Strobing CPCK and STB will provide information about the voltage level with respect to the comparator levels,CPH and CPL.Figure 5. Voltage Force, Measure Current Mode Force CurrentIn the force current mode, the voltage at FIN is now converted to a current through the following relationship:Force Current V R FIN SENSE =/Figure 6 shows a simplified diagram of the PMU when in force current mode. The control loop consists of the force amplifier with the current sense amplifier making up the feed-back path. In this case, voltage at the DUT is sensed across the voltage measure amplifier (Gain = 1) and presented atthe MEASVOUT output.SDUTVFINFigure 6. Current Force, Voltage Measure ModeAD5520Figure 7 illustrates the transfer function of the current force mode.FINFINFigure 7. Current Force Transfer Function Measure VoltageA DUT voltage is tested via the voltage measure amplifier by a window comparator to ensure that CPH and CPL levels are not exceeded. In addition, the DUT voltage is automatically tested against the voltage levels at the clamp, and clamp flags are enabled if the DUT voltage exceeds either of the levels.Short Circuit ProtectionThe AD5520 is designed to withstand a direct short circuit on any of the amplifier outputs.SETTLING TIME CONSIDERATIONSFast throughput is a key requirement in automatic test equipment because it relates directly to the cost of manufacturing the DUT, thus reducing the time required to make a DAC measurement is of upmost importance. When taking measurements using a PMU, the limiting factor is usually the time it takes the output to settle to the required accuracy so a measurement can be taken. DUT capaci-tance, measurement accuracy, and the design of the PMU are the major contributors to this time. Figure 8 shows a simplified block diagram of the AD5520 PMU. In brief, the device consists of a force control amplifier, access to a number of selectable sense resistors, a voltage measure instrumentation amplifier, and a current measure instrumentation amplifier. To optimize the performance of the device, there are also nodes provided where external compensation capacitors are added. As mentioned, mak-ing an accurate measurement in the fastest time while avoiding overshoots and ringing is the key requirement in any ATE system. This in itself provides challenges. The external compensation capacitors set up different settling times or bandwidths on the force control amplifier, and, while one compensation capacitor value may suit one range, it may not suit other ranges. To optimize measurement performance and speed, differences in signal behav-ior on each range and frequency of use of each range need to be taken into account.When selecting a faster settling time, there is a trade-off between the faster settling, overshoots, and ringing. A small compensa-tion value will result in faster settling but may incur penalties in overshoots or ringing at the DUT. Compensation capacitor selection should be optimized to ensure minimum overshoots while still giving good settling time performance.While careful selection of the compensation capacitor is required to minimize the settling time, another factor can greatly contribute to the overall settling of the loop if the feedback loop is broken in some manner and the force control amplifier goes to either the positive or negative rails. There is a finite amount of time required for the amplifier to recover from this condition, typi-cally 85 µs, which adds to the settling of the loop. Ensuring that the force control amplifier never goes into saturation is the best solution. This solution can be helped by putting the device into standby mode at any time the operating mode or range selection is changed. In addition, ensure that the selected output range can supply the required current needed by the DUT.PCB LAYOUT AND POWER SUPPLY DECOUPLINGIn any circuit where accuracy is important, careful consideration to the power supply and the ground return layout helps to ensure the rated performance. The printed circuit board on which the AD5520 is mounted should be designed so that the analog and digital sections are separated and confined to certain areas of the board. If the PMU is in a system where multiple devices require an AGND-to-DGND connection, the connection should be made at one point only. The star ground point should be established as close as possible to the device.This PMU should have ample supply bypassing of 10 µF in parallel with 0.1 µF on the supply located as close to the pack-age as possible, ideally right up against the device. The 0.1 µF capacitor should have low effective series resistance (ESR) and effective series inductance (ESI), such as the common ceramic types that provide a low impedance path to ground at high frequencies, to handle transient currents due to internal logic switching. Low ESR, 1 µF to 10 µF, tantalum or electrolytic capacitors should also be applied at the supplies to minimize transient disturbance and filter out low frequency ripple.Fast switching signals, such as clocks, should be shielded with digital ground to avoid radiating noise to other parts of the board and should never be run near the reference inputs.Avoid crossover of digital and analog signals. Traces on oppo-site sides of the board should run at right angles to each other. This reduces the effects of feedthrough through the board. A microstrip technique is by far the best but not always possible with a double-sided board. In this technique, the component side of the board is dedicated to the ground plane while signal traces are placed on the solder side.REV. A–14–。
