folded cascode op amp design

I successfully completed the classic 2 stage OpAmp design with Miller compensation, and am looking at advanced Op Amp designs.

I started with Folded Cascode Opamp design and am in a confusion not knowing where to start. I went through Johns Martin, and Jacob Baker's books. Both seem totally different in the way Folded Cascode Op Amps are handled - biasing and compensation. I am not sure which one to follow.

Also I am in search of a specification for the opamp parameters to use for the design.

Can somebody please guide me to get started, and provide pointers on how to get started, literature to read for a beginner, and a specification if possible.

Thanks in advance.
 

folded cascode

i think you can find design procedure of the folded cascode in chapter 6 of this book:
CMOS Analog Circuit Design, Phillip E.Allen

yes, but do not follow it blind folded!!

op amp design

Cannot understand the language of the paper.
 

cascode operational amplifier design

i saw that paper, it's only about design automation using evolutionary computing algorithms. this paper can't help you at all.
 

folded cascode opamp

THX for karim365's paper,though i can't see that
actually i am confused two stage opa with folded cascode when it comes to simulate~~~
