A novel digital-domain adaptive calibration technique is proposed, which enables mitigation of analog related errors in over-sampled data converter systems. The technique is suited for all types of over-sampled A/D and D/A converters, e.g. multi-bit, 1-bit, PWM, etc. The calibration is done by adaptive fitting of a digital error model to the physical errors, due to component mismatch, etc.
