Abstract
A bias generation circuit for biasing a differential amplifier is disclosed. The bias generation circuit is coupled to the differential amplifier. After determining a common-mode voltage of a pair of differential outputs from the differential amplifier, the bias generation circuit generates a bias voltage, which is proportional to the determined common-mode voltage, to the differential amplifier such that the common-mode input voltage range of the differential amplifier is extended to as far as the rail-to-rail voltage.
