Title: Young-Ho Kwak: Innovator in Phase Detection and Clock Recovery Technologies

Introduction

Young-Ho Kwak is a distinguished inventor based in Seoul, South Korea, recognized for his significant contributions to the fields of phase detection and clock recovery circuits. With an impressive portfolio of five patents, he has made a remarkable impact on the technology industry through his innovative solutions.

Latest Patents

Among Young-Ho Kwak's latest patents are two notable inventions. The first is a linear phase detector and clock/data recovery circuit, which includes an up/down pulse generator that operates in response to received data signals and a recovered clock signal. This invention is pivotal in generating up and down pulses that have pulse widths proportionate to the phase differences between data signal transitions and the edges of the clock signal, enabling effective data recovery even in the presence of significant jitter.

The second patent pertains to a clock generator designed to reduce long-term jitter. This invention incorporates a controller, a digital phase-locked loop (PLL) circuit, a charge pump PLL circuit, and a divider. The controller generates a division factor and an initial clock signal based on a low-frequency reference clock. The digital PLL circuit, in turn, generates a secondary clock signal, while the charge pump PLL circuit produces multiple clock signals. Ultimately, the divider generates a high-frequency clock signal based on the phase selection and the generated internal clock signals.
