Is the method right to judge the CMFB's stability?
Jun 19th, 2007, 1:42am  
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.
