Title: Zhen-Yu Song: Innovator in Digital Lock Detection and Delay Locked Loops

Introduction

Zhen-Yu Song is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of digital lock detectors and delay locked loops. With a total of 5 patents to his name, Song continues to push the boundaries of innovation in technology.

Latest Patents

One of his latest patents is the "Digital lock detector for phase-locked loop." This invention focuses on a digital lock detector that works in conjunction with a phase-locked loop (PLL) to generate a feedback clock based on a reference clock. The digital lock detector comprises a match detector and an arbiter. The match detector checks for clock transitions within a predetermined time window and generates a match signal accordingly. The arbiter counts the number of successive match signals and produces a lock signal when a specified threshold is exceeded.

Another notable patent is the "Delay locked loop with common counter and method thereof." This invention involves a delay locked loop circuit designed to delay an input clock to synchronize with a delay clock. The circuit includes a frequency divider, multiple delay components, a phase detector, and a counter. The phase detector identifies phase transitions between the final delay clock and the input clock, while the counter generates a count value based on these transitions.
