What is CMRR? Explain briefly.

Answer Posted / daniel joel

CMRR(common mode
rejection ratio) is the ratio of
differential mode gain to the
common mode gain. Actually
in differential amplifier it
should amplify the difference
of the two input signals and
reject the common signals
applied at both ends. CMRR
indicates the efficiancy of the
differential amplifier. Ideally
the CMRR value must be
infinite
