The definition of CMRR in Gray's book is Adm/Acm and which is Adm/Acm-dm in Razavi's book, where Acm-dm means differential gain from common input. How can we distinguish the two different definition?

My opinion is that Gray's is more ideal for mismatch cann't be simulated by spice, but Razavi's is more pratical because differential signal from OPAMPs, easpecial for full-differential OPAMPs, is so useful that Acm-dm will be more meaningful. Mismatch is also taken into account.

Do u think so?
