Latest Patents

Yu Yang holds a patent for a "Reference Timing Signal Oscillator with Frequency Stability." This invention involves an input reference timing signal oscillator of a phase-locked loop that utilizes a computer algorithm to adaptively model the multiple frequencies of an oscillator following a training period. The oscillator is integral to a phase-locked loop, with its oscillation frequency controlled in response to the phase detector output. The computer algorithm processes the control signal applied to the oscillator and updates the model characteristics related to aging and temperature, employing techniques such as a Kalman filter. This predictive model serves as a reference to correct the oscillator's frequency when no input reference timing signal is available. The algorithm allows for the use of oscillators with low stability performance as reference oscillators in cellular base stations.
