1. A frequency modulator circuit, comprising:

  • a frequency oscillator incorporating a tank circuit and operative to generate a resonating waveform;

    a delay circuit coupled to said frequency oscillator and operative to generate a delayed version of said resonating waveform;

    a feedback loop coupled to said frequency oscillator and said delay circuit, said feedback loop operative to inject said delayed resonating waveform back into said tank circuit; and

    wherein said modulator circuit frequency is determined by a duration said resonating waveform is delayed by said delay circuit.
