Latest Patents

One of his notable patents is the "Low jitter high phase resolution PLL-based timing recovery system." This invention features a low jitter, high phase resolution phase lock loop that incorporates a ring oscillator-type voltage-controlled oscillator (VCO). The design operates at a characteristic frequency M times higher than the required output clock frequency. Multi-phase output signals are derived from the VCO and selected through a Gray code multiplexer before being divided down to the output clock frequency by a divide-by-M frequency divider circuit. Operating the VCO at frequencies exceeding the output clock frequency allows for jitter averaging across a timing cycle M. This approach also reduces the number of output phase taps by a scale factor M, without compromising the phase resolution or granularity of the output signal. Yee Ling Felix Cheung holds 1 patent.
