Abstract
Provided is a delta-sigma modulator including a first integral unit configured to integrate an input analog signal, a second integral unit configured to integrate a signal output by the first integral unit, a quantizer configured to quantize a signal output by the second integral unit, a DA converter configured to perform DA conversion on an output of the quantizer and output a feedback signal to be fed back to the first integral unit, and a control unit configured to perform control to cause the first integral unit and the second integral unit to perform different integral operations during a first period and a second period, in which the second integral unit is configured to receive the feedback signal output by the DA converter via the first integral unit and integrate the feedback signal during the first period and the second period.
