Abstract

Power consumption of a successive-approximation type analog to digital converter is reduced. A system is provided with an analog to digital converter and a power-supply voltage generation unit. In the system provided with the analog to digital converter and the power-supply voltage generation unit, the analog to digital converter compares an analog signal with a reference signal and outputs frequency information indicating the number of times of comparison. Also, in the system, the power-supply voltage generation unit generates power-supply voltage on the basis of the frequency information output by the analog to digital converter and supplies the same to the analog to digital converter.
