Question & Answer
Choose the Best Answer
A high CMRR can compensate for low PSRR, reducing non-linear distortion.
High PSRR guarantees low non-linear distortion regardless of CMRR.
Both high CMRR and high PSRR are essential to minimize non-linear distortion in precision applications.
Low CMRR is preferable to ensure better PSRR and reduce non-linear distortion.
Understanding the Answer
Let's break down why this is correct
A good op‑amp needs both high CMRR and high PSRR. Other options are incorrect because The idea that a strong CMRR can make up for a weak PSRR is a mix‑up; Thinking PSRR alone guarantees low distortion ignores common‑mode errors.

Definition
While op-amps do not have infinite gain in practice, their high gain allows for reliable circuit design using negative feedback. Op-amp gain specifications vary between models, and practical op-amp circuits rely on predictable gain behavior.
