一.半导体器件

包括半导体特性，半导体二极管，双极结性三极管，场效应三极管等

导电性介于良导电体与绝缘体之间，利用半导体材料特殊电特性来完成特定功能的电子器件。

二.放大电路的基本原理和分析方法：1.原理：单管共发射极放大电路；双极性三极管的三组态---共射 共基 共集；场效应管放大电路－－共源极放大。分压自偏压式共 源极放大，共漏极放大，多级放大，2方法 直流通路与交流通路；静态工作点的分析；微变等效电路法；图解法等等。

三.放大电路的频率响应

单管共射放大电路的频响－－下限频率，上限频率和通频带频率失真波特图多级放大电路的频响

四.功率放大

互补对称功率放大电路—— OTL（省去输出变压器），OCL（实用电路）

五.集成放大电路

放大电路（amplification circuit）能够将一个微弱的交流小信号（叠加在直流工作点上），通过一个装置（核心为三极管、场效应管），得到一个波形相似（不失真），但幅值却大很多的交流大信号的输出。实际的放大电路通常是由信号源、晶体三极管构成的放大器及负载组成。

偏置电路，差分放大电路，中间级，输出级。

六.放大电路的反馈

正反馈和负反馈

负反馈：四组态——电压串联，电压并联，电流串联，电流并联负反馈。（注意输出电阻和输入电阻的改变）

负反馈的分析：Af=1/F（深度负反馈时）

七.模拟信号运算电路

理想运放的特点（虚短虚地）；

比例运放（反向比例运放,同向比例运放，差分比例运放）；

求和电路（反向输入求和，同向输入求和）

积分电路，微分电路；

对数电路，指数电路；

乘法电路，除法电路。

八.信号处理电路

有源滤波器（ 低通LPF，高通HPF。带通BPF，带阻BEF）

电压比较器（过零比较器，单限比较器,滞回比较器，双限比较器）

九.波形发生电路

正弦波振荡电路（条件，组成，分析步骤）

RC正弦波振荡电路（RC串并联网络选频特性）

LC 正弦波振荡电路 （LC并联网络选频特性电感三点式电容三点式）

石英晶体振荡器

非正弦波振荡器（矩形波，三角波，锯齿形发生器）

十.直流电路

单相整流电路

滤波电路（电容滤波，电感滤波 ,复式滤波）

倍压整流电路（二倍压整流电路，多倍压整压电路）

串联型直流稳压电路

是涉及连续函数形式模拟信号的电子电路，与之相对的是数字电路，后者通常只关注0和1两个逻辑电平。“模拟”二字主要指电压（或电流）对于真实信号成比例的再现，它初来源于希腊语词汇αν?λογο?，意思是“成比例的.
