Hello All,
I am designing a three stage amplifer NMF and am running into Gain Margin issues. I can't find anywhere in books or on the web how much is a good Gain Margin. Everyone always just talking about PM which I totally understand. Does anyone have any papers or places to look?
My Phase margin in 65+ but I am still getting ringing in the time domain. I am seeing a Gain Margin greater then -9dB solves my problems.
Is there a rule of thumb? is -9dB the min? What do people usually design with?
