Hello all,
I have a strange problem:
I run stb analysis for my circuit (opamp buffer) for all corners. I found for some corners my phase plot start at 0 instead of 180 degree, while the location for the poles are still correct, so I can still have correct PM.
Has somebody also experienced same thing? and what is the cause?
thanks in advance,
