question :- source follower based common mode feedback circuit

[cmos_ajay]

Hello ,
Attached is the picture of a 'source follower based common mode feedback circuit'. I had seen this in a text book but the explanation was inadequate.

Can someone let me know only the name of the original IEEE paper or technical document where this circuit is explained ??
I would like to also know the frequency compensation network used for the amplifier that uses this common mode feedback scheme.
Thanks.

I never seen this kind of CMFB before, but it looks like one from Gray, Hurst, Meyer "Analysis and Design of Analog ICs" 4th ed. page 827, fig. 12.17.

Do you have an example of fully designed folded cascode amplifier with class AB push pull stage ?? I wanted it for study purpose only.
Basically I am looking at the choice of currents , the sizing of devices based on various parameters etc....
Thanks.
