第六章 Field-Effect Transistors:介绍场效应管的构成、放大原理和特性,场效应管放大器直流偏置电路分析。6.1场效应管的概念及结构:本节介绍场效应管,Field Effect Transistor,简称FET,顾名思义,它是利用输入电压产生的电场效应,来控制输出电流的,所以又称之为电压控制型器件。
6.2JFET的工作原理:本节讲分两种情况讨论结型场效应管的工作原理。
6.3转移特性曲线及重要关系:一般来说,一个器件的特征曲线,有三种,一种叫伏安特性曲线,一种叫传输特性曲线,一种叫转移特性曲线。
6.4MOSFET的工作原理:结型场效应管,是利用耗尽层的宽度的变化,来调整导电沟道的宽窄,以控制漏极电流的大小,而MOS型场效应管则是利用半导体表面的电场效应,由感应电荷的多少改变导电沟道的宽窄,来控制电流的大小。
6.5MOSFET的转移特性及本章总结:本节主要介绍MOSFET的转移特性,并对本章进行一个总结。
