Incremental delta-sigma modulator

An incremental delta-sigma modulator comprising:

• an analog integration unit including multiple integrators connected in series and configured to integrate an analog signal, each of the multiple integrators having a first-order or higher-order feedback coefficient;
• a quantizer configured to quantize a signal output from the analog integration unit;
• a DA (Digital-to-Analog) converter configured to convert a digital signal output from the quantizer into a feedback analog signal and output the feedback analog signal to the analog integration unit;
• a digital integration unit including multiple integrators connected in series and configured to integrate the digital signal from the quantizer, each of the multiple integrators having a first-order or higher-order feedback coefficient;
• and
• a controller configured to reset each of the multiple integrators included in the analog integration unit and the multiple integrators included in the digital integration unit for each series of integration operations, wherein
• at least one of the multiple integrators included in the digital integration unit has a feedback coefficient greater than 0 and less than 1.
