摘　　要：为了准确直观的理解4种典型功率放大电路的电路特性,文中研究了基于Multisim的功率放大电路的仿真测试。首先介绍了Multisim软件常用的分析方法。其次通过Multisim平台建立了4种功放电路的仿真模型,对其进行了瞬态分析和傅里叶分析。仿真结果表明,在基本型功放电路前端串接运算放大器可以提高电路稳定性,减小电路的交越失真。In order to accurately intuitively understand the circuit features of the four typical power amplifier circuits, this paper studies the simulation test of power amplifier circuit based on Multisim. Firstly ,it introduces commonly used analysis method about Multisim software. Secondly, simulation model of the four power amplifier circuits is established by Multisim platform, transient analysis and Fourier analysis are proceeded . The simulation results show that series- connecting an op-amp in the front of the basic amplifier circuit can improve the stability of the circuit and reduce the distortion of the the circuit.
