A self-calibrating analog-to-digital converter (ADC). The ADC includes multiple component ADCs to generate respective digital representations of an input signal in response to respective timing signals that are offset in phase from one another, each component ADC having a gain setting that controls a...http://www.google.com/patents/US7283074?utm_source=gb-gplus-sharePatent US7283074 - Pilot-tone calibration for time-interleaved analog-to-digital converters
