CONCURRENT WIRELESS POWER TRANSMISSION AND NEAR-FIELD COMMUNICATION
First Claim
1. An electronic device, comprising:
- an antenna configured to resonate in a magnetic near-field and generate an induced current during resonance;
rectifier circuitry coupled to the antenna to rectify the induced current from the antenna during resonance; and
Near-Field Communication (NFC) circuitry coupled to the antenna to demodulate any data on the induced current.

Abstract
Exemplary embodiments are directed to wireless power transfer and Near-Field Communication (NFC) operation. An electronic device includes an antenna configured to resonate at an NFC frequency and generate an induced current. The electronic device further including rectifier circuitry and NFC circuitry 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, rectifying the induced current into DC power for use by an electronic device, and demodulating the induced current concurrent with rectifying to determine any data for the NFC.
