PSpice system simulation application in electronic circuit design

This paper introduces simulation analysis types and detailed steps of PSpice simulation software applied in the design of electronic circuit by the two examples of RC sinusoidal oscillator and four-order Butterworth filter. The simulation result of circuit performance analysis conforms to the theory calculation, which shows that PSpice software has the analysis function of time domain and frequency domain, and provides the reliable theory analysis tool for electronic circuit. Because of powerful simulation performance, excellent convergence, and high efficient and accurate simulation, PSpice software is not only good at the system circuit simulation, but also is welcomed for prospective application.
