Title: Innovations of Shin Chung Chen

Introduction

Shin Chung Chen is a notable inventor based in Los Gatos, California. He holds a total of four patents, showcasing his contributions to the field of technology and engineering. His work primarily focuses on advancements in phase detection and charge pump circuits.

Latest Patents

One of his latest patents is the "Interleaved pulse-extended phase detector." This invention addresses the challenges of faster clock speeds by increasing the pulse width of the pump-up and pump-down pulses in a Hogge-type phase detector without dividing the clock. The mechanism involves dividing an NRZ data stream into two interleaved data streams, which are processed through two series of flip-flops. By connecting exclusive-OR gates to these flip-flops, the invention achieves longer transition times through alternate transitions. Additionally, delay circuits are incorporated to compensate for clock-to-data output delays.

Another significant patent is the "Loop filter capacitor multiplication in a charge pump circuit." This invention presents a charge pump circuit that utilizes a small loop filter capacitor. It achieves this by providing multiple currents that combine to create the desired current. A switching circuit directs one of the currents through the capacitor while managing the others through resistors. This innovative approach allows for a smaller current through the capacitor, resulting in a more compact design.
