By using Muhisim simulation software platform, the amplifier circuit is designed and the simulation analysis is carried on to the circuit. By adjusting the amplifier circuit parameters, the simulation test is conducted to the circuit on the analysis of the signal amplification, saturation distortion and cutoff distortion. Through the analysis of the characteristics of the amplitude frequency and phase frequency, the corresponding conclusion is made on the circuit amplification characteristics. With the circuit spectrum analysis, the amplitudes of DC component, fimdamental component and each hannanic are obtained. The paper explores the better and more widely use of simulation software in the circuit analysis design.
