- a)fluctuates
- b)increases
- c)decreases
- d)stays the same
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
When negative feedback is used, then the gain bandwidth product of an ...
Applying the feedback will reduce the gain but increase the bandwidth hence, the gain bandwidth product = Av x f. he remains constant for any voltage feedback amplifier.
The correct answer is: stays the same

When negative feedback is used, then the gain bandwidth product of an ...
Explanation:
The gain bandwidth product (GBW) of an Op-Amp is the product of its open-loop gain and the bandwidth at which that gain is valid. It is a measure of the amplifier's ability to amplify signals at different frequencies.
What is negative feedback?
Negative feedback is a technique used in electronic circuits to reduce distortion, increase stability, and improve the overall performance of an amplifier. It involves feeding a portion of the output signal back to the input in such a way that it opposes the input signal.
Effect of negative feedback on the gain bandwidth product:
When negative feedback is applied to an Op-Amp, it reduces the overall gain of the amplifier. This reduction in gain allows the amplifier to operate over a wider bandwidth. As a result, the gain bandwidth product of the Op-Amp remains the same.
Reasoning:
1. Negative feedback reduces the gain of the Op-Amp.
2. The bandwidth of the Op-Amp remains the same.
3. Since the gain bandwidth product is the product of gain and bandwidth, if the gain decreases, the bandwidth must increase proportionally to keep the gain-bandwidth product constant.
4. Therefore, the gain bandwidth product of the Op-Amp stays the same when negative feedback is used.
Summary:
When negative feedback is applied to an Op-Amp, it reduces the gain of the amplifier but keeps the bandwidth the same. As a result, the gain bandwidth product remains unchanged.
