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.
