I'm making folded cascode amplfier and common mode feedback circuit to bias output level.
If i make output common mode level 1.75, then each my amplifier output is always almost 1.75v ,not average of two output level without changing my input voltage level.
is my structure not right?
i attach my circuit
Thank you.
