Patent abstract
A structure and related design structure for providing a common mode feedback to a differential amplifier are disclosed. A common mode feedback amplifier is connected to a differential amplifier to provide common mode feedback voltage thereto. An input of the common mode feedback amplifier is shorted to an output terminal of the differential amplifier during a sampling phase, and is coupled to the differential output voltage through two matched capacitors during a holding phase.
