Abstract

A receiver including a first differential sense amplifier configured to amplify an input differential data signal to generate an output differential data signal; a first set of one or more differential decision feedback equalizer (DFE) taps configured to modify the output differential data signal based on a set of one or more differential tap signals, wherein the first set of one or more differential DFE taps affect an output common mode voltage associated with the output differential data signal; and a compensation circuit configured to adjusts the output common mode voltage to compensate for the effect on the output common mode voltage by the set of one or more differential DFE taps. The compensation circuit includes reference and replica receivers to generate reference and replica output common mode voltages, and a feedback circuit to adjust the output common mode voltage based on the reference and replica output common mode voltages.
