Abstract
A distortion correcting analog to digital converter (ADC) system includes a plurality of ADCs configured to convert an analog signal to a plurality of digital ADC outputs, wherein the plurality of ADCs are configured to generate a composite signal based on the plurality of ADC outputs, there is an offset between a first one of the plurality of ADC outputs and a second one of the plurality of ADC outputs, the offset causing distortion in the composite signal. The system further includes an adaptive self-linearizer configured to receive the composite signal, and to perform self-linearization based on the composite signal to correct for the distortion in the composite signal. Generating a distortion corrected digital signal includes converting an analog signal to a plurality of digital signals; generating a composite signal based on the plurality of digital signals; wherein there is an offset between a first one of the plurality of ADC outputs and a second one of the plurality of ADC outputs, the offset causing distortion in the composite signal. The method further includes sending the composite signal to an adaptive self-linearizer and performing self-linearization based on the composite signal to correct for distortion in the composite signal.
