Title: Innovations of Chun-Wei Hsu in Phase-Locked Loop Technology.

Introduction

Chun-Wei Hsu is an accomplished inventor based in Plano, TX (US). He has made significant contributions to the field of electronics, particularly in the development of phase-locked loop (PLL) technology. His innovative work has led to the creation of a patent that enhances the performance of all-digital phase-locked loops.

Latest Patents

Chun-Wei Hsu holds a patent for an "Ultra-low power instant lock phase lock loop (PLL)." This invention focuses on reducing the locking time of a type-II all-digital phase-locked loop (ADPLL) circuit. The system operates by receiving a reference signal with a specific frequency and setting a digitally controlled oscillator (DCO) to a target frequency that exceeds the reference frequency. The DCO generates an output signal that is utilized to create a feedback signal. A time-to-digital converter determines the initial phase difference between the reference signal and the feedback signal. Subsequently, a digital initial phase compensation circuit adjusts this phase difference to nearly zero, significantly reducing the locking time of the ADPLL circuit. This innovation allows the ADPLL circuit to reach a steady-state condition in ten or fewer cycles of the reference signal.
