System and method of analog-to-digital converters

摘要

An analog-to-digital converter system that includes a pipeline of successively-cascaded signal converters, each operating alternatively in a first circuit configuration and a second circuit configuration, an error estimator coupled to the pipeline to receive the digitized error for estimating an amplifier gain of the present signal converter stage, and a code aligner/corrector that temporally aligns and corrects the digital codes received from the successively-cascaded signal converters to provide a digital out of the ADC system.
