Question
双极性结型晶体管放大电路DC分析的步骤:[...]
Answer

BJT放大电路的DC分析的目的是给定放大电路的电源电压\(V_{CC}\)和偏置电阻,计算放大电路工作点的分析过程。其具体步骤为:

1. 将电路中的电容替换为开路,把同一电源分开,画出DC等效电路
2. 对DC等效电路中的输入环(Input loop)和输出环(Output loop)分别应用KVL进行分析
3. \(V_{BE}\)视为0.7V,计算\(I_{B}\rightarrow I_{C}\rightarrow V_{CE}\).
- 当输出环中\(V_{CE}=0\)时,集极饱和电流\(I_{C}=I_{Csat}\).
