摘要

Concurrent adaptive procedure digital offset calibration comparators analog to digital converters (ADCs).; The object of the present invention is an adaptive procedure for calibrating the offset of comparators in analog to digital converters (ADCs). The technique adjusts implemented by a digital low cost control the effective threshold voltage of the comparators or transition without affecting the natural signal path, and therefore without interrupting the A / D conversion of the analog input. It is therefore a technique of concurrent calibration.
