Dr. Yifeng Wu (Transphorm, USA)
"High efficiency GaN power devices: The technology & business opportunities"
Dr. Yifeng Wu received his Ph.D. degree from University of Santa Barbara in 1997 with a thesis in GaN power High-Electron-Mobility-Transistors (HEMTs). He served as a lead scientist in GaN microwave and millimeter-wave power devices at WideGap Technology LLC and Cree Inc. for 11 years. He joined Transphorm in 2008 and is now Vice President of product development and applications.
Dr. Wu has been a pioneer in GaN Electron Devices since his Ph.D. studies in 1995. He was the first to demonstrate a GaN microwave power transistor [EDL 1996] and multiple times extended the record of the highest power density of a solid-state transistor [EDL 1998, IEDM 1999, EDL 2004, DRC 2006]. His contribution to GaN Electronics spans from basic device process development to cutting-edge device designs, from >30 GHz millimeter-wave power HEMTs to 600+ V high-efficiency power switches, from sub-dB low-noise amplifiers to multi-kW power converters. He holds 40 patents and has authored many high-impact papers resulting in more than 3000 citations in Google Scholar.
