With a total of 5 patents to his name, Garvik continues to push the boundaries of innovation in his industry.
Latest Patents
One of his latest patents is focused on oscillator regulation. This invention provides a method for controlling the bias current of an oscillator. The method includes acquiring or determining a digital representation encoding a bias current. It also involves carrying out an algorithm to update the digital representation if the oscillation amplitude is measured, by one or more peak detectors, to be outside of upper and lower thresholds. Additionally, the apparatus is arranged to control the bias current of an oscillator using this method, including one or more peak detectors and a current digital to analogue converter.
Another significant patent is the fast-locking all-digital phase-locked loop (ADPLL) and its applications. This invention is designed for radio receivers, transmitters, or transceivers. The ADPLL comprises a time-to-digital converter for generating a digital time signal based on an external reference clock signal and a feedback signal. It also includes a switched capacitor digitally controlled oscillator (SC-DCO) for generating a radio frequency signal used as the feedback signal. The phase-locked loop controls the SC-DCO based on the digital time signal to achieve phase and frequency lock, with digital processing means configured to maintain a lookup table defining various switching configurations of the SC-DCO.
