which choice is correct?

Question

Gain and bandwidth of an op amp is
a) Independent of each other
b) Gain decreases as bandwidth decreases
c) Gain increases as bandwidth increases till some extent after which stability decreases

Answer 1

Actually, none of the above

In an op amp, the Gain-bandwidth product is constant.
So, when Bw increases, gain decreases and vice versa.

"To a first approximation, the gain of a typical op-amp is inversely proportional to frequency. This means that an op-amp is characterized by its gain-bandwidth product. "

Answer 2

c

Answer 3

B)
