;;A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistors terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Following its development in the early 1950s the transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things.;From_/wiki/Transistor;The Bipolar Junction Transistor: BJT;;共发射极;平衡态下的能带图;PNP型???体管工作原理;PNP型晶体管工作原理;放大及开关功能;二. 场效应晶体管;各种接触对半导体电导的调控作用;FET;;;;金属氧化物半导体场效应晶体管 MOSFET----分类;以p型半导体为例;;;n - type substrate;n - type substrate;双极集成电路 MOS集成电路 BiMOS集成电路; CMOS逻辑单元;CMOS逻辑单元器件结构图;Introduction of CMOS;作业
