<p>Disclosed is a delta-sigma modulator to minimize power consumption generated in double sampling. A processing procedure is performed to output an analog signal with a digital signal. An adaptive current control part determines consumption power required for the operation of an integrator. For this, a maximum current is supplied in a range which has the greatest change in the waveform output of the integrator. A supply current gradually decreases according to a counting operation in the remaining range.</p> |
