Abstract
A flash ADC circuit may include a reference ladder providing reference signals and a plurality of comparators, each providing an output based on a comparison of a pair of input signals to a pair of reference signals. At least one pair of the comparators may receive the same pair of reference signals with a different orientation of the reference signals at each of the comparators. The flash ADC may include a switch network for swapping the pair of reference signals between the pair of comparators.
