I am designing a folded cascode opamp with a single-ended output and that has
both NMOS and PMOS input differential stages (for wide input common mode range).
All the circuits I see, however, have a differential output. Is the bottom design
a correct implementation of a single-ended output?

 

Is there a mistake in the schematic?
The MOSFET in the top right corner of the picture has it's gate connected to the output, and the source and drain connected to Vdd. :-?
 

Is i possible to design a two stage folded cascode OPAMP with 150db gain???
which topology to use??
Application: Sample and hold amplifier
