Abstract
A radio frequency (RF) circuit comprises an antenna operably coupled to receive an RF signal, a power harvesting circuit operable to generate a first power source from the RF signal, a tank circuit coupled to the antenna and a tuning circuit. The tank circuit includes a selectively variable impedance and the tuning circuit is adapted to dynamically vary the selectively variable impedance of the tank circuit based on resonance of the RF circuit and frequency of the RF signal to substantially align the resonance of the RF circuit with the frequency of the RF signal. When the resonance of the RF circuit is substantially aligned with the frequency of the RF signal, the power harvesting circuit generates a second power source from the RF signal such that the second power source is greater than the first power source.
