Parametric analysis
This example shows the effect of varying input resistance
on the bandwidth and gain of the clipper circuit by:
• Changing the value of R1 to the expression {Rval}.
• Placing a PARAM part to declare the parameter Rval.
• Setting up and running a parametric analysis to step
the value of R1 using Rval.
Figure 22 Clipper circuit with global parameter Rval.
This example produces multiple analysis runs, each with
a different value of R1. After the analysis is complete, you
can analyze curve families for the analysis runs using
PSpice.
Note
Parametric Analysis is
not supported in PSpice
