Question: What is the effect of negative feedback on the bandwidth of an operational amplifier?

Options:

Correct Answer: Increases bandwidth

Solution:

Negative feedback in an operational amplifier increases the bandwidth of the amplifier.

What is the effect of negative feedback on the bandwidth of an operational amplifier?

What is the effect of negative feedback on the bandwidth of an operational amplifier?

Step 1: Understand what an operational amplifier (op-amp) is. It is a device that amplifies electrical signals.
Step 2: Learn about negative feedback. This is when a portion of the output signal is fed back to the input in the opposite phase.
Step 3: Know that negative feedback helps to stabilize the gain of the op-amp, making it more consistent.
Step 4: Realize that when negative feedback is applied, the op-amp can handle a wider range of frequencies effectively.
Step 5: Conclude that because of this ability to handle more frequencies, the bandwidth of the op-amp increases with negative feedback.
