Zach Griffith

Zach Griffith (Senior Member, IEEE) received the Ph.D. degree in electrical engineering from the University of California Santa Barbara (UCSB), Santa Barbara, CA, USA, in 2005. From 2005 to 2008, he was a Project Scientist at UCSB designing and fabricating record bandwidth InP HBTs. He is currently a mm-wave and THz IC Design Engineer with the Teledyne Scientific Company, Thousand Oaks, CA, USA. Since joining Teledyne Scientific in 2008, his efforts shifted to InP-transistor-based MMIC and PA design. For over 16 years he has participated in the development of InP HBT technology and high-frequency MMICs which employ it. His design accomplishments include mm-wave op-amps for highly linear low-GHz amplification, efficient broadband E-, W-, D-, and G-band high power amplifiers, and other benchmark circuits having demonstrated state-of-the-art performance. He has authored and coauthors over 125 publications and holds six patents associated with this work.
