Title: Dae-Seung Jeong: Semiconductor Circuit Inventor

Introduction

Dae-Seung Jeong is an inventor based in Seoul, South Korea, whose patent work focuses on phase detection and clock-and-data recovery in semiconductor circuits. He is associated with Samsung Electronics Co., Ltd. and holds 3 patents.

Latest Patents

Jeong’s listed patent work includes “Phase Detection Circuit and Method Thereof and Clock Recovery Circuit and Method Thereof.” The invention describes a phase detection circuit that adjusts the data rate of an input signal and selectively enables reference and error signals. It is designed to support higher operating speeds in semiconductor circuits, including when an internal combinational logic circuit operates more slowly, and may be used in a clock-data recovery circuit.

Another listed invention, “Recovery of Clock and Data Using Quadrature Clock Signals,” describes a quarter-rate phase detector. Four latches capture data at different times according to quadrature clock signals. An error circuit combines selected latched signals to produce intermediate signals, and a multiplexing unit selects an intermediate signal for output as a phase-error signal. A related method uses similar features.
