Hi guys,
I see a lot of posts talking about the phase margin of an inverting opamp as beta*open loop gain. Here beta is the feedback factor. Lets say I have an ideal opamp in ltspice since I am using the universal opamp 2 model. A(open loop) is fixed and does not vary with frequency. Neither does the compensation network , assuming it is made of resistors only. How do I find the phase margin of such a circuit?
