A digital calibration technique for DAC mismatches in delta-sigma modulators


A digital calibration technique is proposed for DAC mismatches in delta-sigma (DeltaSigma) modulators. The delta-sigma modulator works as an incremental ADC in the calibration mode. The DAC mismatches are found by solving linear equations and are compensated digitally. The technique can be used in d......
