Delta-sigma modulator and control method thereof

A control method for a delta-sigma modulator, the delta-sigma modulator comprising:

• a first integrator configured to integrate an analog signal;
• a quantizer configured to quantize a signal output from the first integrator;
• 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 first integrator;
• and
• a controller configured to control the first integrator to repeatedly perform a series of integration operations, wherein
• the series of integration operations includes at least a first integration operation and a second integration operation, and
• the control method comprises:
• controlling, by the controller, the first integrator to perform the first integration operation as an integrator having a first feedback coefficient;
• controlling, by the controller, the first integrator to perform the second integration operation as an integrator having a second feedback coefficient;
• and
• performing, by the controller, the first integration operation and the second integration operation at least partially simultaneously.
