Title: constant-gm bias circuit
Post by blue111 on May 6^th, 2019, 7:41am

I am doing a study on Improvements in biasing and compensation of CMOS opamp.

Do you guys know how to come up with the equation for R_DS4C ?

Someone else had derived the answer , but his derivation still have some mistakes, where his final expression should not have square root.
