Title: Kuen-Suey Hou: Innovator in Phase Locked Loop Technology

Introduction

Kuen-Suey Hou is a notable inventor based in Yunlin, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of phase locked loop (PLL) technology. With a total of 3 patents to his name, Hou's work has had a considerable impact on various applications in the industry.

Latest Patents

One of his latest patents is for a high-resolution phase locked loop. This invention generates a phase locked signal and adjusts its frequency according to an incoming signal. The PLL includes an oscillator for generating the phase locked signal and a frequency detection module that is electrically coupled to the oscillator. The frequency detection module features a pattern detector that identifies two regular patterns in the incoming signal. A counter calculates the number of periods of the phase locked signal corresponding to the distance between these patterns. A comparator then compares this number with a predetermined value to generate a control signal, which is used to adjust the frequency of the phase locked loop signal.

Another significant patent is a sampling clock generator for BCA data decoding. This device provides a sampling clock that is proportional to the actual rotation speed of a disk. The generator includes a frequency counter that counts the number of pulses of a reference clock for each period of a rotation speed indicating signal from a spindle motor. It generates a counting value, which is then divided by a predefined value to produce a divided value. The frequency divider generates the sampling clock by dividing the frequency of the reference clock according to the divided value and adjusting the phase of the sampling clock based on the BCA reproducing signal.
