Abstract

An analog-to-digital converter circuit including an analog-to-digital converter and calibrating circuit, preferably in the form of a digital logic, for the auto-calibration of the analog-to-digital converter. This configuration produces a very high quality analog-to-digital converter with a very low surface area requirement. The calibrating circuit corrects any errors of the analog-to-digital converter outside or inside of the analog-to-digital converter.
