operational amplifier

Amplifier increases the ---------of the signal

• amplitude

• time period

• frequency

• none

operational amplifier performs ---------- operation

• logical

• mathematical

• analytical

• none

•If applied input , we get output without phase shift in----

• inverting amplifer

• non inverting amplifier

• differential amplifier

• none

An ideal operational amplifier has

• infinite input impedance

• zero output impedance

• infinite bandwidth

• both a and b

•It is the voltage that must be applied between the two input terminals of an op-amp to null the output.

• output bias voltage

• output offset voltage

• input bias voltage

• input offset voltage

CMRR for ideal opamp is

• infinite

• small

• large

• zero

slew rate for practical opamp is

• 50v/us

• 0.5v/s

• 0.5v/us

• none

The unit of slew rate is

• hertz divided by time

• volts divided by time

• time divided by volts

• none

Bigger the slew rate

• zero output

• faster the opamp

• slower the opamp

• none

0.5 V/μs means the Op-amp takes ----- to reach an output of 0.5 VOR

• 2 μs

• 10 μs

• 1 μs

• none
