Research Topics


SiC JFET technology for control IC's in space based systems enable the possibility of temperature-tolerant, rugged, radiation-hard circuit operation. Additionally, it offers the possibility of combining with SiC power devices, a high level of integration, reduced parts count, reduced cost and weight in satellite systems. SemiSouth Laboratories, Inc. plans to transfer critical JFET IC technology developed at Mississippi State University to prototype status, and work with key DoD customers to provide early adaptation of the technology. Will further SiC I.C. development, especially in integrated control electronics which are needed for high-temperature sensors and power modulators under distributed control.
