What is CMRR? Explain briefly.
Answer Posted / meenakshi patwal
cmrr is common mode rejection ratio.it is the efficiency of an
opamp to reject common mode signals.a high value of vocm i.e common mode output offset voltage for given vcm results in poor cmrr.value of cmrr for 741 is 90 db.
acm=vocm/vcm
cmrr=20 log(ad/acm)
ad=vo/vd where vd=v1-v2
