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.

摘要： A circuit for generating a modulated signal is disclosed. The circuit includes a constant current source. The circuit further includes a first switch that is coupled to the constant current source. The circuit also includes a second switch that is coupled to the first switch and a ground. The first switch and the second switch are coupled to a third switch. The third switch is coupled to a first integrated circuit pad. The first integrated circuit pad is defined to be used for coupling the third switch to a resonance circuit.

摘要： Circuitry separates a modulation signal into digital sign and magnitude signal components. The digital magnitude signal is converted to an analog magnitude signal. The analog magnitude signal is the mixed with an in-phase or quadrature carrier signal under the influence of the digital sign signal and routed to a driver output stage.
