To make a reduction in power consumption and shortening of start-up time compatible with each other, at starting an electronic circuit.

An apparatus including one or a plurality of circuits includes a first circuit, a first capacitor, a charge storage part and a charge supplying means. The first capacitor stabilizes the operation of the first circuit. The charge storage part stores charges prior to the start of the first circuit. The charge supplying means supplies the charges stored in the charge storage part to the first capacitor, prior to the start of the first circuit, to charge the first capacitor.
