<p>Provided is a sigma-delta modulation circuit comprising: an integration circuit which has a first terminal and a second terminal, and which integrates voltage supplied by way of the first terminal; a first DAC section which supplies a first reference voltage to one terminal of a first resistance, and alternately supplies a first voltage obtained at the other terminal of the first resistance to the first terminal or the second terminal; and a second DAC section which supplies a second reference voltage to one terminal of a second resistance,and alternately supplies a second voltage obtained at the other terminal of the second resistance to the second terminal or the first terminal. When the first DAC section supplies the first voltage to the first terminal, the second DAC section supplies the second voltage to the second terminal. When the first DAC section supplies the first voltage to the second terminal, the second DAC section supplies the second voltage to the first terminal.</p> |
