In an operational amplifier circuit, which of the following statements accurately describes the relationship between common-mode rejection ratio (CMRR), power supply rejection ratio (PSRR), and non-linear distortion when designing for high precision applications?

In high‑precision op‑amp design, a high CMRR ensures that any voltage that appears on both inputs does not appear at the output, while a high PSRR guarantees that fluctuations in the supply rails do not translate into output error; both of these ratios reduce external error sources. However, neither CMRR nor PSRR directly controls the op‑amp’s own non‑linear distortion, which arises from transistor mismatches, finite bandwidth, and slew‑rate limits. Consequently, even if CMRR and PSRR are excellent, a circuit can still suffer from distortion that limits the attainable accuracy. Designers therefore choose devices with low distortion specifications (e. g.
