An Opamp has a CMRR of 10^{4}. The value of the difference gain A_{d} is 10^{5}. estimate the value of the common mode gain A_{c. }

Step 1

As given in the question value of common mode rejection ratio (CMMR) is 10^{4}.

And the value of differential gain A_{d} is 10^{5}.

Step 2

Although formula of CMMR is

Step 3

Hence, plugging the given value...
