Abstract:
1. A power generator capable of being driven by a reference signal having a predetermined frequency, the power generator comprising: a voltage-controlled oscillator configured to deliver a signal having a frequency that varies in response to a provided voltage signal; a frequency generator, coupled to the voltage-controlled oscillator, configured to receive the signal from the voltage-controlled oscillator, configured to receive the reference signal and to receive a power signal, the frequency generator further configured to generate a waveform that is delivered to drive a power generation circuit that generates the power signal; a frequency comparator, coupled to the voltage-controlled oscillator, configured to receive the reference signal and to receive the signal from the voltage-controlled oscillator, and also configured to adjust the frequencies of the reference signal and the signal delivered by the voltage-controlled oscillator, wherein the adjustments are made to correlate the reference signal and the signal from the voltage-controlled oscillator, and wherein the frequency comparator is also configured to detect differences in frequency between the frequency-adjusted signals of the voltage-controlled oscillator and the reference signal, and wherein the frequency comparator is also configured to deliver the provided voltage signal to the voltage-controlled oscillator.
