Abstract
In one aspect, an electronic device for continuous and simultaneous powering and data transfer is provided, the electronic device comprising: an inductive power receiver operable to generate a power signal from a sensed magnetic field, the power signal; an LC tank and diode pair electrically coupled to the power receiver and operable to obtain the power signal, the LC tank and diode pair cooperating to generate a corresponding clipped signal thereof; and an antenna comprising a high-pass filter, the antenna electrically coupled to the diode pair and operable to emit a pulse-train by high-pass filtering the clipped signal.
Claims8
An electronic device for continuous and simultaneous powering and data transfer, the electronic device comprising:
- an inductive power receiver comprising:
- a resonator having an inductive receiving coil for receiving an externally induced magnetic field and correspondingly generating a resonating current;
- a rectifier electrically coupled to the resonator to convert and store a portion of the resonating current to a DC voltage;
- and
- a data transmitter coupled to the inductive power receiver, the data transmitter comprising:
- clipping diodes for limiting a power signal received from the inductive power receiver to a threshold voltage to produce a clipped signal;
- and
- an antenna electrically coupled to the clipping diodes and configured to emit a pulse train corresponding to the clipped signal.
