Patent number: 12184292Abstract: A phase locked loop (PLL) includes a phase detector configured to receive a reference signal and a feedback signal, wherein the reference signal has a reference frequency, sample the feedback signal, and output a phase detection signal indicative of a phase of the feedback signal. A voltage controlled oscillator is configured to generate an output signal based on the phase detection signal. The output signal has an output frequency greater than the reference frequency. Feedback circuitry is configured to detect a signal edge of the output signal and selectively supply, once per cycle of the reference signal, the detected signal edge of the output signal as the feedback signal.Type: GrantFiled: July 19, 2023Date of Patent: December 31, 2024Assignee: The Regents of The University of MichiganInventors: Matthew R. Belz, Lu Jie, Seungheun Song, Michael P. Flynn
