Answer Posted / adesh bandhu
CMMR is abbreviated as common mode rejection ratio.
it means cmmr of an amplifier tells the ablility to
amplify the differance signal more than the common signal
at the input of the two terminal of the amplifier.
so high value of cmmr is required ideally infinity. it
means the reduction of noise at the input.
CMMR=[AD/AC]
AD= differential gain of the amplifire.
AC= common mode gain of the amplifire.
IN decibel
CMMR(log)=20log[base10](ad/ac)
