Common Mode Feedback in Amplifiers by SiddharthJain is a document available to read on EtoBox.

Differential amplifiers provide several benefits including cancellation of common mode signals and even-order harmonics. They have an increased signal swing compared to single-ended amplifiers. However, differential amplifiers require common mode feedback (CMFB) to stabilize the common mode output voltage, as it will otherwise drift to the supply rails causing distortion. CMFB circuits use an error signal derived from the average of the two outputs to adjust an internal common mode voltage and maintain the
