3 Consider a differential amplifier. We desire the common-mode output to be less than 1 percent of the differential-mode output. Find the minimum decibel common-mode rejection ratio to fulfill this requirement if the differential-mode gain Adm = 1,000. Let vi = sin(2,0007 t) + 0.1 sin(1207 t) v2 = sin(2,0007 t+ 180°) +0.1 sin(1207t) vị + v2 = Adm(v1 – vz) + Acm* 2
