AC sweep analysis
The AC sweep analysis in PSpice is a linear (or small
signal) frequency domain analysis that can be used to
observe the frequency response of any circuit at its bias
point.
Setting up and running an AC sweep analysis
In this example, you will set up the clipper circuit for AC
analysis by adding an AC voltage source for a stimulus
signal (see Figure 18) and by setting up AC sweep
parameters.

To change Vin to include the AC stimulus signal
1 In Capture, open CLIPPER.OPJ.
2 Select the DC voltage source, Vin, and press D to
