Cambridge GaN Devices

CGD, a spin off from the Cambridge University, is a fabless semiconductor company on a mission to shape the future of power electronics by delivering the most efficient and easy-to-use transistor.

CGD designs, develops, and commercialises GaN transistors and ICs enabling a radical step change in energy efficiency and compactness and is suitable for high volume production.

Cambridge GaN Devices was founded in 2016 by Prof. Florin Udrea and Dr. Giorgia Longobardi. The company is headquartered in Cambridge, UK.


CGD is developing a range of GaN transistors that are customised for key applications in market segments such as consumer and industrial Switch Mode Power Supply (SMPS), lighting, data centres and automotive HEV/EV.

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 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 our proprietary technology.


CGD has raised $9.5M in a Series A funding on Feb 18, 2021. The round was co-led by IQ Capital, Parkwalk Advisors and BGF, with participations from Foresight Williams, Cambridge Enterprise, Martlet Capital and others.
