Abstract
The charging circuit includes an antenna circuit receiving radio waves, a rectifier circuit rectifying AC voltage generated in the antenna circuit to generate DC voltage, and a power supply circuit adjusting the magnitude of the DC voltage and charging a rechargeable battery using the adjusted DC voltage. The charging device may further include a charge control circuit controlling the power supply circuit so as to prevent overcharge of the rechargeable battery. The rechargeable battery may be charged by application of DC voltage to a pair of terminals, or it may be charged wirelessly in such a manner that an oscillation circuit and an output antenna circuit are additionally provided.
