Design and Implementation of Simulation Platform for Analog Circuits Based on SimElectronics

A virtual simulation experimental platform based on Simulink/SimElectronics is designed and implemented to improve the learning effect and scientific research efficiency for students, so that simulation of various analog circuits can be completed by MATLAB, the commonly used software. The method and process of simulation experiment on the platform are shown through the example of a negative feedback amplifier. The experiment can simulate the actual situation of the circuit and the data and signal waveforms of quiescent and dynamic operation analysis can be achieved, the influence of negative feedback to the circuit performance are verified just as the theoretical analysis. The results show that the process of simulation based on this platform is the same with that of actual hardware experiments with clear, visual and accurate results. This kind of experiment also can reduce the cost and improve experiment flexibility.
