摘要：In a delta sigma modulator including first and second integration circuitsconnected in cascade, each as a component thereof, first and second power sourceterminals for supplying first and second different power source voltages to the first andsecond integration circuits are provided. The first power source voltage is supplied to the

former-stage first integration circuit having a SNR which is largely affected by themagnitude of the power source voltage. The second power source voltage lower thanthe first power source voltage is supplied to the latter-stage second integration circuithaving a SNR which is not largely affected by the magnitude of the power source voltage.
