Title: The Innovations of Gee-Kung Chang
Introduction
Gee-Kung Chang is a notable inventor based in New Providence, NJ, with a significant contribution to the field of electronics. He holds a total of four patents, showcasing his expertise and innovative spirit in developing advanced technologies.
Latest Patents
One of his latest patents is a switch utilizing a solid-state relay. This invention combines a solid-state relay with a control circuit to create a switch that is bilateral and linear through the origin. It is designed to withstand large current or voltage surges and can be toggled either electrically or optically. The relay portion consists of either a pair of or two subsets of DMOS transistors, which cooperate to form a pair of oppositely poled thyristors. The control circuit ensures well-regulated turn-on and turn-off of the relay while providing good immunity against high voltage transients on the switch's main terminals. Additionally, it limits the maximum voltage applied to the gate oxides of the transistors.
Another significant patent involves high-speed p-i-n and avalanche photodiodes. These photodetectors utilize a heavily doped buried layer to limit minority carriers generated by incident light, enhancing response time while substantially decreasing dark current. A p-i-n diode of this type, with a 1.1 square millimeter active area, can operate with a 4-volt reverse bias and achieve edge rise and fall times in the 4 nanosecond range.
