Trying to determine how to simulate the S Parameters and Group Delay of an all-pass filter using an Op-Amp. I have the model setup but I am unsure how to obtain the S Parameters since all of the examples that I have found is by using the AC source and running an AC simulation, but this only provides information such as gain. I am more interested… Show more

I haven't watched the video, but you can run an S-parameter simulation of both passive and active devices, including an op amp. The linear behavior of the op amp will be characterized by its quiescent bias point, if applicable.
