Latest Patents

One of his latest patents is titled "Digital word representative of a non-integer ratio between the respective periods of two signals." This invention involves a phase-locked loop circuit that utilizes a comparator to receive a target digital word representative of a non-integer target ratio between a main signal and a reference signal. The circuit includes a digitally-controlled oscillator that delivers an output signal, with a return loop coupled between the output of the oscillator and the comparator. The comparator generates a digital word representing the non-integer ratio between the periods of the reference signal and the output signal. The oscillator adjusts the frequency of the output signal based on the comparator's results.

Another significant patent is the "Method and device for generating a signal by fractional frequency locked loop." This method includes a cyclical succession of measurement and correction phases. During the correction phase, a frequency divider is deactivated, and the control of an oscillator is adjusted based on an error signal, with the output signal from the oscillator forming the desired signal.
