GaN Class-F Amp
GaN-based Class-F amplifier
Our research efforts cover a wide spectrum of high frequency electronics from novel electronic materials and high-speed devices to complex circuits and sub-systems. UCSB has a very strong program in compound semiconductor materials and devices, and most of our research efforts make use of extensive infrastructure and collaborations in this area. In general, our work is aimed at developing enabling materials and device technologies and new circuit architectures for making high frequency circuits faster, more efficient, with higher power and increased functionality, as compared with existing state-of-the-art.
Electronics and Photonics: microwave and millimeter-wave circuits and devices, GaN electronics for RF and power switching, thin-film ferroelectrics and applications, electromagnetic theory and antennas
Professor York's research involves applying new materials advances to RF and power electronics. His group is developing high-power/high-efficiency electronics using wide band-gap (GaN) semiconductor technology, building on extensive expertise at UCSB in this area. He is co-director of the ONR MURI Center MINE (Millimeter-wave Initiative for Nitride Electronics). He is also a pioneer in applying thin-film ferroelectric technology for use in frequency-agile RF/wireless systems. He was awarded an IEEE MTT-S Outstanding Young Engineer Award in 2004, and received an Office of Naval Research Young Investigator Award in 1996. Dr. York's teaching interests and responsibilities focus mainly on electromagnetic theory and analog circuits.
