when u use in large signal,one side of u'r amplifier works.so, all of current goes to one side.in large signal mode one of M1 or M3 is ON and another is OFF.
in folded cascode compensation capacitor and load capacitor is same.so you must use positive fedback gain circuit.it cause high unity gain frequency and nice Phase Margine.

if you want increase the campensation capacitor,unity gain will be decrease.
but compilers are different with together.it means if u want learn 8051 compiler it have spatial statment that u cant use them for other compilers.i advise learn mikroc compiler for PIC or CCS for PIC or codvision for AVR microcontrollers.
no, there is no dac block in micrcontrollers
but you can use pwm in this way:
exchange the registers of adc with pwm and then filter it with a lowpass fiter.
at the end you can have an analoge signal.
