1. A method of demodulating a signal, comprising the steps of:

  • adding a third harmonic to a modulated signal;

    detecting a peak amplitude of the modulated signal and the third harmonic;

    generating, by a reference ramp generator, a reference ramp when the peak amplitude is detected;

    detecting an inflection in the modulated signal and the third harmonic;

    sampling the reference ramp when the inflection is detected to produce a sampled value; and

    holding and outputting the sampled value.
