摘要： Exemplary embodiments are directed to wireless power transfer and Near-Field Communication (NFC) operation. An electronic device (400) includes an antenna (402) configured to resonate at an NFC frequency and generate an induced current. The electronic device further including rectifier circuitry (404) and NFC circuitry (410) each concurrently coupled to the induced current. The rectifier circuitry configured to rectify the induced current into DC power for the electronic device and the NFC circuitry configured to demodulate any data on the induced current. A method for concurrent reception of wireless power and NFC includes receiving an induced current from an antenna (602), rectifying the induced current into DC power for use by an electronic device (604), and demodulating the induced current concurrent with rectifying to determine any data for the NFC (606).

摘要： A power transmitter is configured to wirelessly transfer power to at least one power receiver. The power transmitter includes at least one excitation circuit configured to generate a time-varying first magnetic field in response to a time-varying electric current flowing through the at least one excitation circuit. The time-varying first magnetic field has an excitation frequency. The power transmitter further includes a plurality of magnetic oscillators. Each magnetic oscillator of the plurality of magnetic oscillators has a mechanical resonant frequency substantially equal to the excitation frequency. The plurality of magnetic oscillators is configured to generate a time-varying second magnetic field in response to the first magnetic field.
