Abstract

An apparatus for analog-to-digital conversion comprising a first module with a comparator and digital-to-analog converters, and a second module with an amplifier. The apparatus implements input chopping by connecting capacitors to differential inputs through switches, and output chopping via an output chopper. Dynamic refresh is achieved using a switch to periodically connect differential inputs to a voltage reference. The apparatus further incorporates digital common-mode rejection ratio (CMRR) enhancement by processing signals from pseudo-differential first stage analog-to-digital converters.
