Pspice simulation with Op Amp AC circuits

1 Background

  As the continous impact by covid-19, it is not easy to conduct course experiment  in the lab.

2 Problem  Op Amp AC circuits

 

 3 Simulation with pspice

 the software of orCAD can be accessed from the blog in the  CSDN.

3.1 build the model

3.2  set the simulation parameters

3.3 View the results

 We should add the trace with P() (phase angle ,unit:deg).

 View the export result

  Frequency             V(R5:2)               MIN(P(V(R5:2)))      
  1.592300000000e+002  1.028291034021e+000  5.901641766310e+001  

 The result is the same as nodaly analysis.
