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].

Answer: Option B

Explanation:

As we know, Gain Bandwidth, Product = β x A

106 = β x A

20 log A = 20

A = 10' 10

β = 100 kHz.
