stability compensation

Simple miller compensation suffer from weak PSRR. So usually current buffer or voltage buffer approaches are used. There are many different techniques u can read about them:

For 2 stage we can use:
1) dominant pole compensation
2) parallel compensation
3) simple miller compensation
4) simple miller compensation with zero nulling resistor
5) simple miller compensation with current buffer (cascode compensation)
6) simple miller compensation with voltage buffer
7) multipath miller zero cancelation
Cool feedforward and others
