摘要：
A digital calibration technique is proposed for DAC mismatches in delta-sigma (Delta Sigma) 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 double-sampling delta-sigma modulators as well.
