Question

Define common mode rejection ratio.

Answer 1

The common mode rejection ratio (CMRR) of a differential amplifier (or other device) is a metric used to quantify the ability of the device to reject common-mode signals, i.e., those that appear simultaneously and in-phase on both inputs.

Answer 2

The common mode rejection ratio (CMRR) of a differential amplifier (or other device) is a metric used to quantify the ability of the device to reject common-modesignals, i.e., those that appear simultaneously and in-phase on both inputs.
