Latest Patents

One of his latest patents is titled "Fast-locking all-digital phase-locked loop and applications thereof." This invention provides an all-digital phase-locked loop (ADPLL) designed for radio receivers, transmitters, or transceivers. The ADPLL includes a time-to-digital converter that generates a digital time signal based on an external reference clock signal and a feedback signal. It also features a switched capacitor digitally controlled oscillator (SC-DCO) that produces 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, while digital processing means maintain a lookup table defining various switching configurations of the SC-DCO corresponding to different frequencies.

Another significant patent is for a "Near field communication device with voltage regulation comprising an integral controller and a variable shunt resistance." This electronic device is designed to receive near-field communication signals and includes first and second antenna connection terminals with a variable shunt resistance connected between them. It features a peak detector that detects the amplitude of incoming near-field communication signals and produces a peak signal dependent on the amplitude. The device also includes a comparator that generates an error signal based on the difference between the peak signal and a reference signal. An integral controller varies the shunt resistance in response to the integral of the error signal, regulating the received voltage and reducing voltage swing.
