Hi, I have attached the circuit of three stage Op-Amp using Nested Gm-C compensation. Could anyone explain what is the exact job of stage encircled by red color, and how can this stage design. Please help.....
 

Hi erikl..

what is the need for this isolation here..

does it need to avoid feedforward voltage..

and how it is done?
thanks

-gmf1 is a feed-forward stage!

I'd suggest to study the literature on Nested Gm-C Compensation and Nested Miller Compensation given in the References of the a. m. PDF file.
