ELECTRONIC DEVICE

WIPO Patent Application WO/2016/194090

A1

The present invention provides a power supply technology with low power consumption to supply an appropriate voltage to a plurality of semiconductor chips from a single power supply circuit. This electronic device provided with a plurality of circuit blocks and a power supply circuit that supplies power to the plurality of circuit blocks is characterized by comprising: a voltage determining unit that determines the power voltages of the plurality of circuit blocks; a detection result outputting unit that combines the determination results on the respective power voltages by the voltage determining unit, to output a detection result; an output setting unit that determines the output voltage by the power supply circuit on the basis of the output by the detection result outputting unit; and an individual voltage adjusting unit that adjusts the power voltages in the respective circuit blocks, wherein the output voltage by the power supply circuit is adjusted by combining the determination results on the power voltages of the plurality of circuit blocks, and the power voltages in the circuit blocks are adjusted respectively by the individual voltage adjusting unit.
