Abstract: A data converter is disclosed. The data converter includes a loop-filter, a quantizer, an analog dynamic element matching (DEM) shuffler, a digital DEM shuffler and a feedback digital-to-analog converter. The loop-filter receives analog signals from an analog input. The quantizer then converts the filtered analog signals from the loop-filter to digital signals at a digital output. The analog DEM shuffler shuffles a set of analog threshold levels of the quantizer to yield a set of partially shuffled digital data at an output of the quantizer. The digital DEM shuffler shuffles the set of partially shuffled digital data from the output of the quantizer to yield a set of shuffled digital data. The feedback digital-to-analog converter converts the set of shuffled digital data to a set of analog data to be fed back to the loop-filter.
