Abstract
A circuit device includes: a first storage control unit which receives power from a power receiving unit which receives power by electromagnetic induction, to perform control of storing charge in a first charge storage unit; a second storage control unit which performs control of storing charge in a second charge storage unit; and a power source supply unit which supplies power source to a system device based on charges stored in the first charge storage unit and the second charge storage unit. The second charge storage unit is a charge storage unit whose charge storage capacitance is smaller than that of the first charge storage unit. The power source supply unit supplies, at the time of system start-up after the start of power reception, power source based on the stored charge of the second charge storage unit to the system device.
