基本放大电路的组成
上图画出共射极基本放大电路。它由三极管、电阻、电容和直流电源组成。
由于三极管基本放大电路的放大元件是半导体三极管，要使它具有放大作用，必须外加直流电源，并保证三极管的发射极有正向偏置电压，集电结有反向偏置电压。
另外，输入信号和输入电极之间有信号通路，输出电极和负载之间有信号通路。
因为直流电源对交流信号呈现非常小（接近为0）的电阻，因此要避免交流信号与输入、输出电极相联的信号被直流电源短路。所以直流电源和输入、输出电极之间接有足够大的阻抗。
我们学习的三种基本放大电路的构成，都具有上述特点。
2)．基本放大电路的工作特点：
（1）电路中既有直流，又有交流。直流提供静态工作点，交流是被放大的信号；
（2）电路由线性元件和非线性元件组成，不能直接用线性电路的分析方法分析放大电路；
（3）三极管必须始终工作在放大状态，以保证被放大的信号不失真。
