Question

explain the concept of gain bandwidth product​

Answer 1

Answer:

The gain bandwidth product, GBW, is defined as the product of the open loop voltage gain and the frequency at which it is measured.The GBW is constant for voltage feedback amplifiers. It does not have much meaning for current feedback amplifiers, because there is no linear relationship between gain and bandwidth.

When designing an op amp circuit, a figure known as the op amp gain bandwidth product is important. The op amp gain bandwidth product is constant for voltage-feedback amplifiers. Therefore decreasing the gain by a factor of ten will increase the bandwidth by the same factor.
