WitrynaWhat is common-mode voltage rejection ratio - CMRR. Common mode rejection ratio (CMRR) of a differential amplifier (or other devices) 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. An ideal differential amplifier would have infinite CMRR.
