Title: Innovations of Yee Ling “Felix” Cheung

Introduction

Yee Ling “Felix” Cheung is an accomplished inventor based in Irvine, CA. He is known for his significant contributions to the field of timing recovery systems. With a focus on enhancing the performance of phase lock loops, Cheung has made strides in reducing jitter and improving phase resolution.

Latest Patents

Cheung holds a patent for a "Low jitter high phase resolution PLL-based timing recovery system." This innovative system incorporates a ring oscillator-type voltage-controlled oscillator (VCO) designed to operate at a frequency significantly higher than the required output clock frequency. By utilizing multi-phase output signals from the VCO and selecting them through a Gray code multiplexer, the system effectively divides down to the desired output clock frequency. This approach allows for the averaging of jitter across a timing cycle, enhancing the overall performance without compromising phase resolution.
