Abstract

A method for wirelessly receiving energy and data, including: a resonation operation of resonating a first frequency power signal transmitted from a transmission apparatus; a reception operation of receiving a second frequency data signal transmitted from the transmission apparatus; a first matching operation of matching input/output impedance upon receiving the first frequency power signal; a rectification operation of rectifying impedance-matched power signal from the first matching operation into a DC current; a second matching operation of matching input/output impedance upon receiving the second frequency data signal; an oscillation operation of outputting a second frequency signal by using the first frequency signal output from the resonation operation, as a reference frequency; and a frequency mixing operation of mixing the impedance-matched data signal from the second matching operation with the signal output from the oscillation operation to restore a baseband data signal.

an oscillator to output a second frequency signal by using a first frequency signal output from the resonator as a reference frequency; and
a mixer to mix an impedance-matched data signal from the second matching circuit with a signal output from the oscillator to restore a baseband data signal.

2. The apparatus of claim 1 , further comprising a load to consume the DC current rectified by the rectifier.

an oscillation operation of outputting a second frequency signal by using the first frequency signal output from the resonation operation, as a reference frequency; and
a frequency mixing operation of mixing the impedance-matched data signal from the second matching operation with the signal output from the oscillation operation to restore a baseband data signal.

5. The method of claim 4 , further comprising a signal amplification operation of amplifying the impedance-matched data signal, after the second matching operation.

6. An apparatus for wirelessly receiving energy and data, comprising:
a resonator to resonate a first frequency power signal transmitted from a transmission apparatus;
