Question: If for an amplifier the common mode input signal is vc, the differential signal id vd and Ac and Ad represent common mode gain and differential gain respectively, then the output voltage v0 is given by
Options
A : v0 = Ad vd – Ac vc
B : v0 = – Ad vd + Ac vc
C : v0 = Ad vd + Ac vc
D : v0 = – Ad vd – Ac vc
