Abstract
An apparatus including analog-to-digital conversion (ADC) circuitry is disclosed. The apparatus includes a plurality of comparators susceptible to offset variation and a shuffler circuit configured to shuffle input sources to the respective comparators. Feedback circuitry is also included and is configured and arranged with the ADC circuitry to detect offset variation in the outputs of each comparators for the shuffled inputs, relative to outputs of the plurality of comparators and compensate for the offset variation in the comparators based on the offset differences between the respective comparators.
