Abstract
An apparatus includes a first half-cell, a second half-cell, a multiplexer and a decision feedback equalizer. The first input stage may be configured to present a first differential input to the first auto-zero stage and the second auto-zero stage. The second input stage may be configured to present a second differential input to the third auto-zero stage and the fourth auto-zero stage. The multiplexer may be configured to receive a first output from the first auto-zero stage, receive a second output from the third auto-zero stage and present a decision feedback input comprising one of the first output and the second output. The decision feedback equalizer may be configured to generate a feedback signal in response to the decision feedback input and present the feedback signal to the first feedback buffer and the second feedback buffer.
