WIRELESS POWER STORAGE DEVICE, SEMICONDUCTOR DEVICE INCLUDING THE WIRELESS POWER STORAGE DEVICE, AND METHOD FOR OPERATING THE SAME

摘要

PROBLEM TO BE SOLVED: To simplify charging of a battery in a power storage device which includes the battery and further to provide a wireless power storage device which can transmit and receive individual information without the task of replacing a battery for drive power supply, which becomes necessary when the battery depletes over time, being performed. SOLUTION: An antenna circuit, a battery which is electrically connected to the antenna circuit via a rectifier circuit, and a load portion which is electrically connected to the battery are provided. The battery is charged when an electromagnetic wave received by the antenna circuit is input to the battery via the rectifier circuit, and discharged when electrical power which has been charged is supplied to the load portion. The battery is charged cumulatively, and the battery is discharged in pulses. COPYRIGHT: (C)2008,JPO&INPIT
