An adaptive digital calibration of multi-step A/D converters
2010
IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS
Preserved Fulltext
A novel digital technique for efficient calibration of static errors in high-speed, high-resolution, multi-step ADCs is proposed. The parameter update within the calibration method is extended to include and correct effects of temperature and process variations. Additionally, to guide the verification process with the information obtained through monitoring process variations, expectation-maximization method is employed. The algorithm is evaluated on a prototype multi-step ADC converter with
