Title: The Innovative Mind of Dung Ho: Pioneering ESD Protection Circuits

Introduction: Dung Ho, an accomplished inventor based in Sunnyvale, CA, has made significant contributions to the field of electronics with his innovative designs. With a remarkable portfolio of three patents, Ho specializes in developing advanced protection circuits for electronic devices.

Latest Patents: Among his latest inventions is an electrostatic discharge (ESD) protection circuit that effectively manages both positive and negative ESD events while allowing signal passage. This circuit is ingeniously designed with a p-channel field-effect transistor (PFET) clamp connected to a protected pin. It incorporates multiple PFETs arranged in a DN-well and an n-channel field-effect transistor (NFET) clamp linked between the ground and the pin through the PFET clamp.

The NFET clamp is composed of a series of NFETs, and a bias network is included to ensure the DN well voltage aligns with the pin voltage when it exceeds ground potential. Additionally, when the pin voltage dips below ground potential, the bias network grounds the DN well voltage. The design also features PFETs connected in parallel between the pin and the NFET clamp, each PFET interfacing with the pin through its ballast resistor, enhancing the circuit’s efficiency and reliability.
