1. A power rectifying circuit comprising:

  • an input for accepting a high frequency, substantially sinusoidal signal lying within a predefined operating frequency range,an output for accepting a load to be energized,a first inductance associated with the input,a first capacitance associated with the input,a network, including a rectifying diode coupling the input to the output, the diode including significant adjunct capacitance,a second inductance included within the network,a second capacitance included within the network and including the adjunct capacitance,the first and second capacitance and the first and second inductance being tuned to obtain first and second frequency response poles in an impedance of the input selected such that the first and second frequency response poles are bracketing a predefined frequency range of the sinusoidal signal and further having network quality adjusted so that a resistive component of impedance at the input is substantially invariant with respect to frequency variations of the high frequency signal over the predefined operating frequency range.
