Abstract
An analog-to-digital converter includes a plurality of slave sampler multiplexers responsive to outputs of a master sampler that receives analog signals and whose output ports connect to integrating threshold comparators having capacitive digital-to-analog conversion offset adjustments for forming an analog-to-thermometer code conversion. A calibration state machine receives outputs of each of the integrating threshold comparators to control the capacitive digital-to-analog conversion offset adjustment of every integrating threshold comparator and to control a calibration digital-to analog converter. A thermometer code to binary code logic decoder receives outputs of each of the integrating threshold comparators and outputs digital samples.
