UNIT 1 Microelectronics and Electronic Circuits1-1Introduction to Microelectronics首先学习KEY WORDS.学习课文英文翻译成中文，并注意学习专业词汇。
Para. 1对太空的探索以及人造地球卫星的发展，增强了人们对减少电子电路的重量和体积的重要性的认识。
另外，即使电流在计算机中流得相当快，但是由于电子元器件之间的互联所导致的信号的时间延迟是不能不考虑的。
如果这种互联在尺寸上能减小，无疑会使计算机的运行速度更快。
Para. 2微电子学主要是使常规电路微型化。
比如一个运算放大器，包括许多彼此互连的分立器件，有二极管，电阻，象这样一个完整的电路，可以制作在一个很小的基片上。
这个完整的微型化的电路就称之为集成电路（IC）。
Para. 3IC体积小，重量轻，坚固耐用，稳定可靠。
它们比同等宏观电路（分立元件电路）需要更少的功耗和更低的电压。
因此，它们可以工作在更低的温度下，而在这种温度下，分立器件可能都不能正常工作，因为温度没有达到正常工作温度范围。
相应地，几乎不会产生寄生电容和延时，因为在IC中，器件之间地互联非常短。
维护起来跟简单，因为，如果在一个IC里边地器件坏了，通常用一个新的IC来替换坏的。
表面技术的大规模生产技术已经降低了许多IC的成本，因此，它们就跟单个晶体管一样便宜。
最后的结果就是，大部分常用的分立器件电路被IC所取代。
Para. 4有两种基本类型的IC：一种是独立IC,一种是薄或厚的膜状IC. 独立IC是构建在单个的半导体晶体的基片里边，通常用的是硅。
薄或厚的膜状IC是形成在一种绝缘材料的表面，像玻璃或者陶器。
还有一种混合的IC所包含的不仅仅是单个的基片。
在这里，这个词“混合”同样也指独立IC和薄或厚的膜状IC结合体。
Para. 5也可根据其功能不同对集成电路进行分类。
数字IC（也称为逻辑IC）通常用作开关，表示接通或关闭。

1 The transistor is what started the evolution of the modern computer industry in motion.晶体管开启了现代电脑工业的革命2 The storage cell only requires one capacitor and one transistor, whereas a flip-flop connected in an array requires 6 transistors.存储单元仅需要一个电容和晶体管，并而不像触发器整列那样需要6个晶体管3 There has been a never ending series of new op amps released each year since then, and their performance and reliability has improved to the point where present day op amps can be used for analog applications by anybody.从此以后每年都有新系列的运放发布，他们的性能和可靠性得到了提升，如今任何人都能用运放来设计模拟电路。
4 This is capable of very high speed conversion and thus can accommodate high sampling rates, but in its basic form is very power hungry.它具有高速转换能力，从而能适应高速采样速率，但它的基本形式非常耗电。
5 During the “on” period , energy is being stored within the core material of the inductor in the form of flux.在”on”阶段，能量以涌浪形式存储在电感的核芯材料里面6 The design goal of frequency synthesizers is to replace multiple oscillators in a system, and hence reduce board space and cost.频率合成器的设计目标是取代系统中多个振荡器，从而减小板卡面积和成本。

Until this time, feedback analysis was done by multiplication and division, so calculation of transfer functions was a time consuming and laborious task. Remember, engineers did not have calculators or computers until the '70s. Bode presented a log technique that transformed the intensely mathematical process of calculating a feedback system's stability into graphical analysis that was simple and perceptive. Feedback system design was still complicated, but it no longer was an art dominated by a few electrical engineers kept in a small dark room. Any electrical engineer could use Bode's methods find the stability of a feedback circuit, so the application of feedback to machines began to grow. There really wasn't much call for electronic feedback design until computers and transducers become of age.1945年HW伯德提出了一套系统方法，用图形化方法来分析反馈系统的稳定性。

What happens when a mobile unit “roams” from cell A to cell B? Since the power level received from the base station in cell A is insufficient to maintain communication, the mobile must change its server to the base station in cell B. Furthermore, since adjacent cells do not use the same group of frequencies, the channel must also change. Called “handoff,” this process is performed by the MTSO. 因为从单元A 因为从单元A的基站接收到的功率 电平不足以维持通信， 电平不足以维持通信，手机必须将 服务器更换为单元B的基站。 服务器更换为单元B的基站。

1.This electron beam sweeps across each line at a uniform rate，then flies back to scan another line directly below the previous one and so on，until the horizontal lines into which it is desired to break or split the picture have been scanned in the desired sequence．电子束以均匀的速率扫描每一行，然后飞速返回去扫描下一行，直到把被扫描的图像按所希望的顺序分割成行。
2.The technical possibilities could well exist，therefore，of nation-wide integrated transmission network of high capacity，controlled by computers，interconnected globally by satellite and submarine cable，providing speedy and reliable communications throughout the word因此，在技术上完全可能实现全国性的集成发送网络。
这种网络容量大，由计算机控制，并能通过卫星和海底电缆实现全球互联，提供世界范围的高速、可靠的通信。
3.Transit time is the primary factor which limits the ability of a transistor to operate at high frequency．渡越时间是限制晶体管高频工作能力的主要因素4.The intensity of sound is inversely proportional to the square of the distance measured from the source of the sound.声强与到声源的距离的平方成反比。
5.The attenuation of the filter is nearly constant to within 0.5 dB over the entire frequency band．该滤波器的衰减近于恒定, 整个频带内的变化在0.5 dB以内。
6.At present, the state of most semiconductor device technology is such that the device design and process technology must be supplemented by screening and inspection procedures, if ultimate device reliability is to be obtained and controlled．目前, 大多数半导体器件的技术尚未十分完善, 以至若要获得并控制器件最终的可靠性, 就必须辅以筛选和检验, 以弥补设计和工艺技术之不足7.Bandwidth of transistor amplifiers vary from about 250 MHz in the L band to 1000 MHz in the X band．晶体管放大器的带宽在L波段约为250 MHz, 在X波段为1000 MHz。
8.The output of the differential amplifier is fed to the circuit’s output stage via an offset-compensation network, which causes the op-amp’s output to center at zero volts. The output stage takes the form of a complementary emitter follower, and provides a low-impedance output.差动放大级的输出通过一个失调补偿网络与输出级相连, 目的是使运放的输出以0 V为中心。
输出级采用互补的射极跟随器的形式以使输出阻抗很低9.Because of the very high open-loop voltage gain of the op-amp, the output is driven into positive saturation (close to +V) when the sample voltage goes slightly above the reference voltage, and driven into negative saturation (close to-V) when the sample voltage goes slightly below the reference voltage.由于运放的开环电压增益很高, 当取样电压略高于参考电压时, 输出趋向于正向饱和状态(接近+V)。
当取样电压低于参考电压时, 输出趋向于负向饱和状态(接近-V)。
10.If the signal source were direct connected instead of capacitor coupled, there would be a low resistance path from the base to the negative supply line, and this would affect the circuit bias conditions.如果信号源和电路不是用电容耦合而是直接相连，从基极到负电源线就会一个低阻通路，并且这将影响到电路偏置状态11.The differential amplifier has a high-impedance (constant-current)“tail”to give it a high input impedance and a high degree of common-mode signal rejection. It also has a high-impedance collector (or drain) load, to give it a large amount of signal-voltage gain (typically about 100 dB).差动放大极有一个高阻抗的“尾巴”（恒流源）以提供高输入阻抗和对共模信号的深度抑制，同时，它还具有一个高阻抗和集电极或漏极负载以提供高的信号电压增益（典型的数据是100dB).12.On the other hand, a DC negative-logic system, as in Figure 3.6(b), is one which designates the more negative voltage state of the bit as the 1 level and the more positive as the 0 level.另一方面, 如图3.6(b)所示, 把比特的较低的电压状态记为1电平, 较高的电压状态记为0电平, 这样的系统称为直流负逻辑系统。
13.For example, to represent the 10 numerals (0, 1, 2, …, 9) and the 26 letters of the English alphabet would require 36different combinations of 1’s and 0’s. Since 25<36<26, then a minimum of 6 bits per bite are required in order to accommodate all the alphanumeric characters.例如，要表示0～9十个数字和英文字母表中的26个字母，就需要0和1的36种不同的组合。
因为25<36>26,所以,为了能表示所有的字母和数字，要求每个字节最少要6个比特。
14.A 1 signifies the existence of a positive pulse in a dynamic positive-logic system; a negative pulse denotes a 1 in a dynamic negative-logic system; a 0 at a particular input (or output) at a given instant of time designates that no pulse is present at that particular moment.在动态正逻辑系统中，1表示有一个正脉冲存在，而在负逻辑系统中，负脉冲表示为1。
不管那种系统，某一时刻在某一输入端（或输出端）的0，均表示此刻无脉冲。
15.Intergraded circuits are also classified according to their functions. Digital or logical IC are used as switches, they are either on or off. In computers the on and off states correspond to 0 or 1.Other IC is called linear or analog IC.也可根据其功能不同对集成电路进行分类。
数字IC(也称为逻辑IC)通常用作开关, 表示接通或关断。
在计算机中, 接通和关断状态分别对应“0”或“1”。
另一种IC被称为线性或模拟IC。
16.The reduction in power dissipation is particularly important where a complex circuit is to be concentrated into a small space. The problem of extracting the heat generated in the circuit may then be a difficult one.减小功率损耗是非常重要的, 其方法是将一个复杂的电子线路集成为一小块。
