Question

A differential amplifier has an open-loop Voltage gain of
120. The input signals are 2.45 V and 2.358. Calculate the output voltage
of the amplifier​

Answer 1

Answer:

Explanation:

Acom=Vo= 24 x 10-3= 8 X 10-3= 0.008Vcom3.0CMRR= 20 log10differential voltage gaindBCommon mode gain=20 log101200.008=20 log1015000= 83.52 dBANS= 83.52 dB.
