The diagram of a full differential opamp with CMFB is in the left I want to know whether it is stable, I broken the point a and make the cmfb point as the input and point a as the output as can be seen in the right. Cla is the load of the point a. Can I judge the stability of the CMFB circuit by seeing the bandwidth and phase margin of the point out? Thank you very much.
