Abstract
A power generation circuit has one of an antenna or a coil that receives an ambient radio wave. A rectifying circuit is connected to the antenna or the coil for rectifying a signal from the antenna or the coil receiving the ambient radio wave. A booster circuit is connected to and boosts an output of the rectifying circuit. A storage circuit is connected to the booster circuit and stores an output power obtained from the rectifying circuit for driving a load without the use of a power source or a battery. A switching circuit is operable in an ON-state thereof to connect the storage circuit to the load when a voltage of the storage circuit is equal to or greater than a preselected voltage.
