US Patent 11231741 Systems and methods for generating clock signals

The present invention is directed to electrical circuits. More specifically, embodiments of the present invention provide a clock generator that includes a source clock generates a source clock signal at a low frequency. A clock multiplier multiplies the source clock signal by a predetermined factor to generate a high frequency clock signal. The high frequency clock signal is corrected by a time adjustment module by applying a compensation signal. The compensation signal is determined by a jitter measurement module, which uses both the high frequency clock signal and a jitter reference signal to determine the compensation signal. There are other embodiments as well.
