Hello, I have designed a two stage op amp with a phase margin of 63° ( with a compensation capacitance) which is sufficient to ensure good stability of the circuit. However, I still have a huge overshoot problem when I use it as a follower. How is it possible if my circuit is stable and how can it be avoided?
Also, when I use it in a summing circuit and apply an AC signal to the input, I get some oscillations in the output signal that I think are related to the overshoot issue.
