What is the most effective way of measuring the input/output impedance of an amplifier in a simulation?
When I know the impedance I want to measure is purely resistive, I usually set up an input signal Vin and a test resistor as a resistive divider with the desired impedance. Then I compare the voltage values of the input/output and work my math to get a number for the impedance.
Is there a better way?
I am using Orcad Capture with PSpice.
