Abstract

The embodiment of the present invention provides a wireless charging and communication circuit and a wireless electronic device, including an electrically connected receiving circuit and a signal processing circuit; the receiving circuit is used to receive the electric energy wirelessly transmitted by the transmitting circuit, and transmit feedback to the transmitting circuit wirelessly according to the electric energy Signal; the signal processing circuit is used for receiving the control signal generated according to the feedback signal and wirelessly transmitted by the transmitting circuit, and processing the control signal. The embodiment of the present invention can supply power to the receiving circuit according to the charging command, and can realize two-way data communication based on the transmitting circuit and the receiving circuit while charging, so as to facilitate real-time understanding of the charging status and realize data transmission while charging.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular, the present invention relates to a wireless charging and communication circuit and a wireless electronic device. Background technique [0002] Passive electronic tags (also known as passive tags) do not have a built-in battery. When they are outside the reading range of the reader, the electronic tags are in a passive state. When they are within the reading range of the reader, they can be charged through a wireless charging circuit. Wireless charging. [0003] In the prior art, it is usually impossible to communicate while charging the passive electronic tag, and it is impossible to know the current charging status in time; in a few cases, communication is possible, but the circuit structure is relatively complicated, and usually only one-way communication can be realized, and it cannot Realize two-way communication. [0004] In addition, the existing wireless chargi...
