A DAC Mismatch Calibration Technique for Multibit Sigma Delta Modulators

Pierre-André Farine, Steve Tanner, Shafqat Ali

A technique for the calibration of DAC (digital to analog converter) mismatch errors in multi-bit Sigma Delta modulators (SDM) is presented. It consists of two parts: the first is a measurement technique to obtain the relative mismatch of each feedback DAC ...
