you have to connect both input to the same AC source and run AC simulation
This will give you common mode voltage gain
then you have to simulate differential gain (regular AC simulation to extract small signal gain) and the ratio of these two will give you CMRR
--------------------------------------------------------------------------------------
but how can i configure the OPAmp to plot the CMRR vs Freq? Has anyone here done it b4, pls give me a suggestion.
thanks in advance.
