| Abstract: | 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. |
