The open-loop gain A of real (nonideal) op-amps is very large at low frequencies but decreases markedly as frequency increases. As a result, the closed-loop gain of op-amp circuits can be strongly dependent on ω = 4 × 103 rad/s determine
a. Common- and differential-mode input voltages.
b. The voltage gains for vS1 and vS2.
c. Common-mode component and differential-mode component of the output voltage.
d. The common-mode rejection ratio (CMRR) in decibels.
e. The common-mode rejection ratio (CMRR) in decibels.
