1. A transmitter comprising:

  • a resonant circuit including at least one capacitor; and

    a driver coupled to drive said resonant circuit,wherein said resonant circuit includes a resonance regeneration system configured to modulate an amplitude of a resonant signal in said resonant circuit such that (a) when an amplitude of said resonant signal is reduced by the resonance regeneration system, energy is stored in the at least one capacitor and (b) when said amplitude is increased by the resonance regeneration system, the energy stored in the at least one capacitor is used to regenerate said resonance signal.
