47.
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
50 kHz
100 kHz
Answer: Option
Explanation:
As we know, Gain Bandwidth, Product = β x A
106 = β x A
20 log A = 20
A = 10' 10
β = 100 kHz.
