第三课 晶体管及其基本电路
现在,晶体管是电子技术中最重要的器件。它们不仅作为独立元件, 而且在集成电路微薄的硅片上可包含成千上万个晶体管
晶体管由3层半导体材料构成:一种类型的薄层在中间,两边分别是另 两种类型。可以有两种排列方式:N型在中间,P型在两边(PNP); P型在 中间,N型在两边(NPN )。中间层称为基极,两边外层分别称为发射 极和集电极(如图1-17所示)
电子信息是当今国内外发展最迅速、技术更新最快的工程领域之一, 电子信息专业英语对学习电子信息新知识和新技术起着非常重要的作 用。

The amount of resistance offered by a resistor is determined by its physical construction [8].
[8].电阻的阻抗是由它的物理结构决定的。
be determined by 由…决定 A carbon composition resistor has resistive carbon packed into a ceramic cylinder, while a carbon film resistor consists of a similar ceramic tube,
For example, gold, silver, and copper have low resistance, which means that current can flow easily through these materials.
9
Glass, plastics, and wood have very high resistance, which means that current can not pass through these
8
Resistance can be written in a number of different ways depending on the ohm rating. For example, 81R represents 81 ohms, while 81K represent 81,000 ohms. The resistance varies in different materials [3]. [3].不同物体的阻抗不同。 vary in … 依据…而变化 。

Notes to the Text
Development of Electronics
[1] vacuum tube:真空管是一种电子元件,因为参与工作的电极被封装在一个真空的玻璃容器 内,所以被称为真空管。在中国大陆,真空管有时会被称为电子管。在香港和中国广东地区, 真空管有时又会被称作“胆”。 [2] a sealed glass in which electrons flow between electrodes separated by vacuum:in which关系 代词在定语从句中做介词宾语时,由介词 + 关系代词引导定语从句。separated by vacuum过去 分词修饰electrodes。句子可以翻译为:在密封的玻璃管中,电子在由真空隔离的电极间流动。 [3] it became possible to amplify and transmit the electrical energy:it代替不定式to amplify and transmit the electrical energy在句中作形式主语。句子可以翻译为:放大和传送电能成为可能。 [4] radio communication:无线电通信。
[5] as more specialized tubes were made for many applications:as引导状语从句,句子可以翻译 为:随着越来越多的适用于各种用途的专门真空管制造出来。

10
Prior to the invention of transistors, digital circuits were composed of vacuum tubes, which had many disadvantages[5].
在晶体管发明之前,数字电路是由真空管组成的,这
有很多不足。
3
There are two types of standard transistors, NPN and PNP, with different circuit symbols [2]. [2].标准的晶体管有两种类型:NPN和PNP, 它们的电路标志不一样。 with different circuit symbols是介词短语作 非限定性的定语,故后置且用逗号与中心词分 开。

pipelining
• A technique where the microprocessor fetches the next instruction before completing execution of the previous instruction, in order to increase processing speed.)
Latest Pentium architecture started out with a 400MHz system bus and 256KB L2 cache (later increased to 800MHz and 2MB). The first models contained 42 million transistors, used the 0.18 micron process and came in 423pin and 478-pin PGA packages. Intel's first Pentium 4 chipset was the 850 and supported only Rambus memory (RDRAM), but subsequent chipsets switched to DDR SDRAM.
• 流水线是一种在前一条指令全部执行完之前就开始取下一条指 令,以提高处理速度的技术。

micron, data width, MIPS
• micron是“微米(百万分之一米)”的意思,和μm一样。Micron值 用于度量相应芯片中的最小线宽。Micron值越小,芯片中集成 的晶体管数量就越多。 data width是指算术逻辑单元ALU的字长。8-bit的ALU可以进行 两个8-bit 数的加、减、乘等运算,32-bit 的ALU可以对32-bit的 数进行操作。外部数据总线的宽度一般和ALU的数据宽度相同, 但也有例外。如8088 的ALU 是16-bit,而其外部数据总线为8bit;而Pentium处理器的ALU 是32-bit,而其外部数据总线为64bit. MIPS Million Instructions Per Second 每秒百万条指令。MIPS是 一个粗略表征微处理器性能的指标。因为现代微处理器的种类 繁多、结构各不相同,MIPS 指标所能反映的信息很有限。

Load in text
• Historically, the linear regulator was the primary method of creating a regulated output voltage. It operates by reducing a higher input voltage down to the lower output voltage by linearly controlling the conductivity of a series pass power device in response to changes in its load. This results in a large voltage being placed across the pass unit with the load current flowing through it. • 在历史上,线性稳压器曾是产生稳压输出电压的主要 方法。通过对级联功率通过器件导电性线性控制以响 应负载变化,线性稳压器将输入高电压降为输出低电 压。这种方法导致在负载电流流经的通过单元两端出 现一个大电压。
