摘要：
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a plurality of digital intermediate signals in response to an analog input signal, a first set of threshold and reference voltages and a second set of threshold and reference voltages, where the threshold and reference voltages of the first set are shifted with respect to corresponding threshold and reference voltages of the second set. The second circuit may be configured to generate a digital output signal in response to the plurality of digital intermediate signals.
