I really really need your help.
I designed the LNA for neural recording. I used capacitive feedback for blocking external DC offset, and pseudo-resistor to make high-pass frequency pole.
To see the performance of LNA, I need to look at factors such as CMRR, PSRR, NEF.
I got the CMRR with differntial gain and the common mode gain just like the piceture below, but how can I get PSRR and NEF of the LNA?
