Title: Innovations of Inventor Hung Pham Le
Introduction
Hung Pham Le is a notable inventor based in San Jose, California. He holds a total of 11 patents, showcasing his significant contributions to the field of technology and engineering. His work primarily focuses on advancements in CMOS technology and electrostatic discharge protection devices.
Latest Patents
One of Hung Pham Le's latest patents is an "Open-drain output buffer for single-voltage-supply CMOS." This invention features an open-drain output buffer that can sustain relatively high voltages applied to an output pad. The design includes floating wells, output switching devices, and well-bias selectors to prevent gate oxide from sustaining voltages greater than a predefined value. The PMOS and NMOS well-bias selectors ensure that the highest or lowest voltage is provided to bias the corresponding well-regions, maintaining safe operating conditions.
Another significant patent is the "Low-voltage CMOS space-efficient 15 KV ESD protection for common-mode high-voltage receivers." This device is strategically placed between true-complement input pins of a differential signal pair and a ground node. It features diode stacks that channel current from an electrostatic discharge event to ground, protecting the complementary receiver node. The design can withstand a 15 kV incident and saves up to 25% in area compared to traditional configurations.
