  • Jitter estimation in phase-locked loops
    Patent number: 8170823
    Abstract: A phase-locked loop is characterized by analyzing phase noise in its output signal while known levels of input phase noise are provided. The resulting data provides intrinsic phase noise and gain of the phase-locked loop. These values provide a general relationship between input phase noise and output phase noise for the phase-locked loop, which allows estimation of output phase noise corresponding to a given level of input phase noise, and allows estimation of input phase noise corresponding to a given level of output phase noise.
    Type: Grant
    Filed: February 8, 2011
    Date of Patent: May 1, 2012
    Assignee: Altera Corporation
    Inventors: Daniel Tun Lai Chow, San Wong, Vincent K. Tsui, Lik Huay Lim, Man On Wong
