What is OP Amp Simulation Techniques and Tests about?
This document describes simulation methods for characterizing operational amplifiers (OP Amps) in SPICE. It discusses how to: 1. Measure offset voltages at the input to ensure the OP Amp is properly biased over its common mode input range. 2. Measure open-loop differential gain by applying differential input signals around the offset voltage. 3. Determine small-signal bandwidth and phase margin by configuring the OP Amp as a follower and analyzing its frequency response. 4. Test output swing by forcin
