Title: Chih-Wei Hsu: Innovator in Electrostatic Discharge Protection
Introduction
Chih-Wei Hsu is a prominent inventor based in Changhua County, Taiwan. He has made significant contributions to the field of electrostatic discharge protection, holding a total of 5 patents. His innovative designs have advanced the technology used in various electronic devices.
Latest Patents
One of Hsu's latest patents is an electrostatic discharge circuit. This circuit includes a discharge switch, a first trigger circuit, and a second trigger circuit. The first terminal of the discharge switch is coupled to a first power domain, while the second terminal is coupled to a second power domain. The first trigger circuit is connected between the first terminal and a control terminal of the discharge switch. The second trigger circuit is linked between the second terminal and the control terminal. When an electrostatic discharge voltage occurs in the first power domain, the second trigger circuit forms a conduction voltage between the second terminal and the control terminal to activate the discharge switch. Conversely, when the electrostatic discharge voltage occurs in the second power domain, the second trigger circuit shorts the second terminal and the control terminal to turn on the discharge switch.
Another notable patent by Hsu is the electrostatic discharge protection apparatus and its operating method. This apparatus consists of a substrate, a first well with a first conductivity type, and a second well with a second conductivity type. The first well is situated within the substrate, while the second well is located within the first well. The apparatus also includes a first doping region, a second doping region, a third doping region, and a fourth doping region, all strategically placed to form a silicon controlled rectifier. The electrostatic discharge current flowing into the first doping region is directed to the fourth doping region through the silicon controlled rectifier.
