An inverting amplifier and a noninverting amplifier are built using the same values of Rf and Rin. Assuming that the op-amps being used in the two circuits have identical common-mode gain values, which circuit will have the higher CMRR?
A) The inverting amplifier
B) The noninverting amplifier
C) Neither. The two CMRR values will be equal.

Question

The noninverting amplifier typically has a higher Common-Mode Rejection Ratio (CMRR) because the common-mode gain in a noninverting configuration is generally lower than in an inverting configuration, while the differential gain remains high, leading to a higher CMRR value.
