Title: Colin Wai Mun Leong: Innovator in Hybrid Frequency Synthesis

Introduction

Colin Wai Mun Leong is a notable inventor based in Livermore, CA (US). He has made significant contributions to the field of frequency synthesis, holding 2 patents that showcase his innovative approach to hybrid phase lock loop technology.

Latest Patents

Colin's latest patents include a "Method and apparatus for a hybrid phase lock loop frequency synthesizer." This invention features a hybrid frequency synthesizer that integrates both an analog phase lock loop (PLL) and a digital PLL, along with a control circuit to manage an output oscillator. The control circuit intelligently assigns control of the output oscillator between the analog and digital PLLs based on their respective states of lock. During the frequency acquisition mode, the digital PLL provides coarse control, while the analog PLL fine-tunes the output during the phase capture mode. The system is designed to ensure a smooth transition to low noise phase lock by the analog PLL during the phase lock mode.

Another significant patent is the "Hybrid analog/digital phase lock loop frequency synthesizer." This invention combines control signals from both the analog and digital PLLs to create a composite control signal that governs the phase and frequency of the output oscillator. The design allows for rapid and accurate acquisition by the digital PLL, followed by a seamless transition to low noise phase lock by the analog PLL.
