OpAmp Open Loop Stability Analysis with Pspice

Hello Harry,

very good application note, thanks!  The appnote is very helpful.

However, the OpAmp circuit I have to analyse is a bit more complex. It is a non-inverting amplifier with RF and RG resistors for Gain setting of 2. The load is a heavy capacitive. Thus, I don't think that the solution for open loop testing provided in the appnote (capacitor applied on negative opamp input) is applicable for my circuit design. Is there a common method for insertion a AC-source and testing the open loop response with Pspice? How can I open the feedback loop for simulation the open loop response?

Thanks in advance
