Answer Posted / louis
ideally the two input terminals must be identical but
practically it is often not possible but effort is put to
make them as identical as possible, that's where cmrr
comes into picture. its ratio of
differential gain of the amplifier
and
common mode gain of the amplifier.
if input are almost identical then common mode gain must be
almost zero, in other words cmrr is infinity....
