Which specification cant be meeted? Is the UGBW?
I have tried this OPamp for practise , and I find the UGBW is a problem....

Added after 3 minutes:

em.....And the slew rate is not easy to get 50v/uS...

Is this folded-cascode?

And, why does it use Rz and Cc ?

How to measure CMRR,DC gain,UGBW,SR,Phase margin,ICMR,Output swing and PSRR for this two-stage folded-cascode op amp?
 

 

Hi smaswi
I have tried this circuit, 0.5pf is enough for compensation. I think there maybe some mistake in your calculation.
from SR=2I/(Cc+Cload)
I=0.5*50e6*(0.5e-12+2e-12)=62.5uA

I think 2I that you mean should be the current of M0.

But, how about Sro?

I don't understand what it means.

What is different between Sr and Sro?
