Frank Chang appointed as Electrical Engineering Department Chairman

Professor M.C. Frank Chang, holder of the Wintek Chair in Electrical Engineering and director of the High Speed Electronics Laboratory, has been appointed chairman of the UCLA Department of Electrical Engineering, effective, August 1.

Prof. Chang has made major contributions to the development of high-speed semiconductor devices and integrated circuits. His work has transformed the landscape of modern high-speed electronics, with benefits for daily life around the globe.

In addition, Prof. Chang has been recognized with several prestigious awards, including election to the National Academy of Engineering in 2008 and received he IEEE David Sarnoff Award for exceptional contributions to electronics in 2006. His work has included the development of GaAs HBT and BiFET devices and power amplifiers used in the production of 2G and 3G mobile phones worldwide. The current generation of phones — and even transceivers — could not be realized cost-effectively without the use of these high-efficiency, high-linearity power amplifiers.

Prof. Chang's pioneering circuit research has resulted in the development of ultra–high-speed and high-frequency RF and mixed-signal circuits for wireless and wired communication. His development of multi-gigabit sample/second analog-to-digital and digital-to-analog conversion has also opened doors for the development of the next generation of digital radars and radios.

His creative techniques for generating Terahertz signals with commercial CMOS technology, which is used in digital logic circuits like microprocessors and in analog circuits such as image sensors and data converters, have paved the way for the future development of low-cost and portable wireless signaling devices (wireless radio, chip-to-chip interconnections) and imagers with unprecedented bandwidth and resolution.

In 1997, following a career in industry, he returned to UCLA Engineering as a faculty member.

Before joining UCLA, he was the Assistant Director and Department Manager of the High Speed Electronics Laboratory at the Rockwell Science Center (1983-1997), Thousand Oaks, California. In this tenure, he successfully developed and transferred AlGaAs/GaAs Heterojunction Bipolar Transistor (HBT) and BiFET (Planar HBT/MESFET) integrated circuits technologies form the research laboratory to the production line (now Conexant Systems and Skyworks).

He received his bachelor's degree in physics from National Taiwan University, his master's in materials science from National Tsing Hua University and his doctorate in electrical engineering from National Chiao-Tung University, Taiwan, R.O.C. He joined the UCLA materials science and engineering department in 1979 as a postdoctoral fellow under professor Alfred S. Yue.

Prof. Chang succeeds Professor Ali Sayed, who served as the department chair of electrical engineering for the past five years.
