Q1:

A 741 type op-amp has a gain bandwidth product of 1 MHz. A non-inverting amplifier using this op-amp and having a voltage gain of 20 dB will exhibit a -3dB bandwidth of

A 50 kHz

B 100 kHz

C

D

ANS:B - 100 kHz

As we know, Gain Bandwidth, Product = β x A  106 = β x A  20 log A = 20  A = 10'  10 β = 100 kHz.
