Abstract:
A common mode feedback (CMFB) loop for a differential amplifier sense an output common mode of a differential circuit and provides feedback to the gates of tail current transistors. Many CMFB loops cannot easily adjust the output common mode voltage and the output common mode may vary over process, voltage, and temperature. An improved CMFB circuit adds a control circuit to control backgates of tail current transistor device(s) of the differential circuit such that the output common mode voltage can be made adjustable.

Claim (Index 19):
The apparatus of  claim 18 , wherein the control means for varying the output common mode voltage comprises means for driving the backgates of tail current devices until the common mode feedback reaches a target output common mode voltage.
