I am going to design a CMFB in two stage folded cascode differential opamp.
according to the , somebody said "we need to have two cmfb circuit in two stage."
is it correct that two cmfb circuit is needed in two stage folded cascode differential opamp?
this opamp is going to use in a S/H circuit of pipeline adc .
which type of cmfb is suitable for me ???
will somebody give me some reference (or paper) of CMFB?

I think you can use one CMFB, but you must take care for the stability of the cmfb.
And I think using two CMFB is better because of less risk of stability.

Check chapter 8 "fully differential amplifiers" in "Analog Design Essentials" by Willy Sansen.
It is a very practical oriented book, and I recommend it highly.
