Title: The Innovative Contributions of Stephen C Su
Introduction
Stephen C Su is a notable inventor based in Huntington Beach, CA (US). He has made significant contributions to the field of technology, holding a total of 7 patents. His work primarily focuses on advancements in switching circuits and infrared detection methods.
Latest Patents
One of his latest patents is for a switching circuit that efficiently manages a low impedance load. This circuit switches the load between a power supply source and ground using a series-connected power MOSFET. The conduction of the MOSFET is controlled by a switching circuit that includes a linear loop, which regulates the switch voltage to a minimum value. This design ensures current flow through the load and the MOSFET. Additionally, the circuit features a current supply in parallel to the MOSFET, which maintains a minimum predetermined current. This current is indicative of the load's current flow under open load conditions. If the load current drops below this threshold, an open load status flag is triggered, indicating that the loop is no longer in regulation.
Another significant patent involves a signal detection method for infrared detectors with a charge readout structure. This method enhances the operation of infrared detectors characterized by a semiconductive substrate of a first conductivity type. The invention includes a detection region defined by a heavily doped backside electrode and a buried layer. It also features a charge coupled device (CCD) readout structure that transfers charge in an epitaxial layer of a second conductivity type. The design prevents harmful double injection and substrate breakdown while allowing for effective detection of radiation.
