摘要
具有稳定静态工作点的单管共射放大电路是模拟电路里的一款经典电路,包含很多的模拟电路知识,其中耦合电容和旁路电容是该电路的重要组成部分。通过电容的特性使电路的交直流通路进行分离,使得该电路的动态性能得到很好的改善。文章将对该电路中耦合电容及旁路电容的工作原理及对频率特性的影响进行深入讨论,并结合仿真软件multisim12进行仿真分析。
A single tube common emitter amplifier circuit with stable quiescent operating point is a classical circuit in analog circuits, which contaios a lot of analog circuit knowledge, and the coupling capacitor and bypass capacitor are the important components of the circuit.The AC / DC path of the circuit is separated by the capacitors,so that the dynamic performance of Ihe circuit is improvedlD this paper, Hie working principle and the influence on fhe frequency characteristics of the coupling cap-acitor and bypass capacitor in the circuit are further discussed,combmed with the simulation software multisiml2 analysis.
