摘要： An object is to provide a power feeding system and a power feeding method which are more convenient for a power feeding user at the power receiving end, without causing increases in complexity and size of devices. An object is to provide a power feeding system and a power feeding method which also allow a power feeding provider (a company) which feeds power (at the power transmitting end) to supply power without waste. A power feeding device which wirelessly supplies power to a power receiver detects the position and the resonant frequency of the power receiver by receiving a position and resonant frequency detection signal using a plurality of sub-carriers having different frequencies from the power receiver, and controls the frequency of a power signal to be transmitted to the power receiver on the basis of the information. An efficient power feeding service can be offered by transmitting a power signal to the power receiver at an optimum frequency for high power transmission efficiency.

摘要： An object of this invention is to provide a semiconductor device (an RFID) with reduced loss of voltage/current corresponding to a threshold value of a transistor, and having a voltage/current rectification property. Another object of this invention is to simplify a fabrication process and a circuit configuration. A rectifier circuit is provided in an element included in a semiconductor device (RFID) capable of communicating data wirelessly. As compared to the case where only a diode is provided, coils are provided between gate terminals and drain terminals of transistors constituting the diode in a rectifier circuit, so that the coils overlap an antenna which receives a radio wave, whereby a voltage output by the rectifier circuit is increased using electromagnetic coupling between the antenna which receives a radio wave and the coils, so that the rectification efficiency is improved.

摘要： A resonant power feeding system that can provide high power transmission efficiency between a power feeding device and a power reception device without dynamically controlling the oscillation frequency in accordance with the distance between the power feeding device and the power reception device. High power transmission efficiency between the power feeding device and the power reception device is obtained by addition of a structure for adjusting the matching condition to both the power reception device and the power feeding device. Specifically, a transmission-reception circuit and a matching circuit are provided in both the power reception device and the power feeding device, and wireless signals for adjusting the matching circuit are transmitted and received through a resonant coil. Thus, the power feeding device can efficiently supply power to the power reception device without adjusting the oscillation frequency.
