[2]

A 741-Type OP-AMP has a gain-bandwith product of 1MHz. A non-inverting

amplifier using this opamp & having a voltage gain of 20db will

exhibit -3db bandwidth of

Answer

[3]

An amplifier using an opamp with slew rate SR=1v/sec has a gain of

40db.If this amplifier has to faithfully amplify sinusoidal signals from

dc to 20KHz without introducing any slew-rate induced distortion, then

the input signal level exceed

Answer

[4] The ideal OP-AMP has the following characteristics

Answer

[5] The approximate input impedance of the opamp circuit which has Ri=10k, Rf=100k, RL=10k

Answer

Answer

[7] Assume that the op-amp of the fig. is ideal. If Vi is a triangular wave, then V0 will be

Answer

A differential amplifier is invariably used in the i/p stage of all

op-amps. This is done basically to provide the op-amps with a very high

Answer

[9] A differential amplifier has a differential gain of 20,000. CMMR=80dB. The common mode gain is given by

Answer

[10]

In the differential voltage gain & the common mode voltage gain of a

differential amplifier are 48db & 2db respectively, then its common

mode rejection ratio is
