How to check the cmfb loop stability?
 

After exploring the earlier articles in this forum, I have the questions.
Why it is said there is no stability problem in sc cmfb?
And, may I use the caps of the sc cmfb be the load cap of OPamp, and be
the frequency compenstation cap in the same time, for example in single
stage folded cascode opamp?

Thanks,
