Opamp compensation - two stage folded cascode opamp

op amp compensation

Hi all,

I am designing a two stage folded cascode opamp. Specification of load capacitor has very high range.
The minimum load cap is 470pF and maximum is 100nF. I am finding it difficult to compensate this opamp. With 470pF load capacitor, the output node becomes second pole and a miller cap will help to compensate this. But with 100nF load cap, the output node becomes first pole and miller cap spoils the phase margin.

Can anyone help me in this design..

Thank you

op-amp compensation

i think u should go for some load compensated architecture
