Abstract
An analog-to-digital converter system,is provided that comprises an analog-to-digital converter pipeline,coupled to a memory system,and a calibration system,. An arithmetic logic unit,receives a raw output from the analog-to-digital converter system,and calibration quantities from the calibration system,to generate a calibrated output. The calibration system,is able to iteratively generate multiple order calibration values that can be used to eliminate capacitor mismatch errors. The techniques described are equally applicable to analog-to-digital converter architectures which resolve multiple bits per stage of the analog-to-digital converter system.
