Hello friends,
I am simulating the CMRR of my amplifier, I am getting the CMRR = 80 dB at DC frequency while the DC differential gain is 103 dB. My amplifier is fully differential amplifier,
How it is possible that CMRR is less than the differential gain ??
Note.. this is the Postlayout simulation results
Thank you in advance
