Title: Innovations of Ruben Undheim
Introduction
Ruben Undheim is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of electronics, particularly in the development of advanced digital systems. With a total of six patents to his name, Undheim's work has had a considerable impact on radio communication technologies.
Latest Patents
One of Undheim's 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, with digital processing means that maintain a lookup table defining various switching configurations of the SC-DCO.
Another significant patent is related to "Clock domain crossing." This invention describes an electronic device with a synchronization system that receives a signal clocked by a first clock signal and a second clock signal, which is offset in phase from the first. The system includes an adjustable delay period to determine whether the next clock edge received is active or non-active. A calibration controller adjusts the delay period based on the clock edge received, ensuring optimal synchronization.
