Question & Answer
Choose the Best Answer
A higher phase margin increases distortion
A lower phase margin reduces distortion
A higher phase margin reduces distortion
Phase margin has no effect on distortion
Understanding the Answer
Let's break down why this is correct
Phase margin shows how close the amplifier is to oscillating. Other options are incorrect because Thinking that a bigger margin makes the circuit louder is a mix‑up; Lowering the margin seems like a quick fix, but it allows the amplifier to swing too far, causing bumps.

Definition
Negative feedback in op-amps involves connecting the output back to the input to achieve self-correction. In negative feedback, the ideal op-amp forces the inverting and non-inverting inputs to be equal, maintaining stability and precise control.
