Cambridge GaN Devices (CGD) is a fabless semiconductor company

Company overview

Cambridge GaN Devices (CGD) is a fabless semiconductor company span-out by Prof. Florin Udrea and Dr. Giorgia Longobardi from Cambridge University in 2016 to exploit a revolutionary technology in power devices. Its mission is to shape the future of power electronics by delivering the most efficient and easy-to-use transistor.

CGD has been created to explore and develop a number of unique opportunities in power electronics made possible by the team’s proprietary application of Gallium Nitride to the silicon-based semiconductor transistor manufacturing process. With silicon transistors widely acknowledged as having attained maximum efficiency, CGD’s power design engineers have developed a range of Gallium Nitride transistors that are over 100 times faster, lose 5 – 10 times less power and are 4 times smaller than existing silicon equivalents.

CGD technology is protected by a strong IP portfolio which constantly grows based on the company's leading innovation skills and ambitions. In addition to the multi-million seed fund and Series A private investments, CGD has so far successfully secured four projects funded by iUK, BEIS and EU (Penta). The technical and commercial expertise of the CGD team combined with an extensive track record in the power electronics market has been fundamental in early market traction of its proprietary technology.
