Hello
I Want to design a folded cascode amplifier with Vdd=1.2 and Vss=0 and input and output dc voltage=0.6. I use following circuit.This is my problem that i suppose input dc voltage =0.6 but gain is not >60.
My technology file in TSMC 0.13um.Vth=0.45.
please help me.
best regards

Hi,
Firstly, try using a simple current source for the tail. That's better. In this case M1 and M5 have more headroom too.
What is your process and Vth?

How much is gain? Does common mode feedback work well?
 

can you post the result of operating point analysis for the ckt. ?
that will help in knowing condn of various transistors..
 

M4/M3 may in linear region
