Abstract
In general, in one aspect, the disclosure describes an apparatus that included a reference generator to receive a differential input signal and generate reference voltages having same common mode as the differential input signal. A replica bias generator is used to generate a bias signal based on the reference voltages. A comparator is used to compare the input signals to threshold voltages that are based at least in part on the bias signal.
