Abstract: Methods, systems, computer-readable media, and apparatuses for spurious information reduction in a data signal are presented. Some configurations include mixing a plurality of analog input signals with different corresponding local oscillator signals to generate a corresponding plurality of converted signals; generating, from each of the plurality of converted signals, a corresponding one of a plurality of sampled signals; frequency shifting at least one signal that is based on at least one of the plurality of sampled signals to obtain, from at least the plurality of sampled signals, a plurality of frequency-aligned signals; and performing a common-mode filtering operation, based on information from the plurality of frequency-aligned signals, to produce a digital output signal.

Abstract: Methods, systems, computer-readable media, and apparatuses for spurious information reduction in a data signal are presented. One example of such an apparatus includes a data converter including a plurality of analog-to-digital converters (ADCs) and configured to produce a plurality of sampled signals, a normalizer configured to obtain a plurality of common-bandwidth signals from at least the plurality of sampled signals, and a common-mode filter configured to produce a digital output signal based on the plurality of common-bandwidth signals.
