Title: Innovations of Kenneth W Ouyang in Electrostatic Discharge Protection

Introduction

Kenneth W Ouyang, based in Huntington Beach, CA, is an accomplished inventor with a notable portfolio comprising 18 patents. His work primarily focuses on innovative solutions in the field of electrostatic discharge (ESD) protection circuits, demonstrating a commitment to enhancing the reliability of integrated circuits.

Latest Patents

Among his latest innovations is the patent for an **Electro-static Discharge Protection Circuit with Bimodal Resistance**. This circuit employs an extended resistive structure featuring bimodal resistance characteristics, integrated seamlessly within an input/output buffer circuit and an electrical contact pad on an integrated circuit. This innovative design functions in two resistance modes: during standard operations, it maintains a low resistance to avoid additional loading on the buffer circuit; during ESD discharges, it switches to a higher resistance, significantly reducing current and protecting the circuit from potential damage.

Another significant patent from Kenneth is the **Capacitively Induced Electrostatic Discharge Protection Circuit**, which utilizes a capacitor and a zener diode to trigger a thick oxide ESD shunt field effect transistor (FET). This mechanism allows for automatic operation; when the voltage triggered by ESD at an input/output node reaches the zener diode's breakdown voltage, the FET activates to divert harmful current away from sensitive components, thereby ensuring robust protection against damaging ESD events.
