It is showing something like hysteresis, 106mV for Input : Low->High, 58mV for Input : High -> Low So adding 1 mV Source to input was not successful. Also, I tried following link https://www.analog.com/en/resources/analog-dialogue/articles/simple-op-amp-measurements.html but simulation failed, it said need more strict time interval. I think offset can be compensated by adding voltage source, but what can i do for hysteresis?

In general, DC gain can be measured by using ac/stb analysis in ADEL. Upvote 0 Downvote
