Abstract
A Provided is an electronic device in which: alternating current power from an RF coil which receives an electromagnetic wave and converts the electromagnetic wave into power is rectified by a diode and a first capacitor; the power is stepped up by a charge pump type step-up circuit; the power stepped up by the step-up circuit is stored in a second capacitor by a charging and discharging circuit; and the stored power is supplied from the charging and discharging circuit to an RF transmission circuit.
