Operational Amplifiers and their Parameters

CMRR of Op Amp Formula (Common Mode Rejection Ratio): One of the more common features of a differential amplifier is its ability to cancel out or reject certain types of undesired voltage signals. Such undesired signals are referred to as “noise” and may occur owing to voltages induced by stray magnetic fields in the ground …
