Dr. Mau-Chung Frank Chang is currently the President of National Chiao Tung University (Hsinchu, Taiwan). He is also the Wintek Chair in Electrical Engineering and Distinguished Professor at University of California, Los Angeles (UCLA). Before joining UCLA, Dr. Chang was the Assistant Director and Department Manager of the High Speed Electronics Laboratory at Rockwell International Science Center (1983-1997), Thousand Oaks, California. In this tenure, he developed and transferred the AlGaAs/GaAs Heterojunction Bipolar Transistor (HBT) and BiFET (Planar HBT/MESFET) integrated circuit technologies from the research laboratory to the production line (later became Conexant Systems and Skyworks). The HBT/BiFET productions have grown into multi-billion dollar businesses and have dominated the cell phone power amplifier and front-end module markets for the past twenty years (currently exceeding 10 billion units/year and exceeding 50 billion units in the last decade).
Throughout his career, Dr. Chang’s research has primarily focused on the research & development of high-speed semiconductor devices and integrated circuits for RF and mixed-signal communication radar and imaging system applications. He was the principal investigator at Rockwell in leading DARPA’s ultra-high speed ADC/DAC development for direct conversion transceiver (DCT) and digital radar receivers (DRR) systems. He was the inventor of the multiband, reconfigurable RF-Interconnects for Chip-Multi-Processor (CMP) inter-core communications and inter-chip CPU-to-Memory communications. He was the 1st to demonstrate a CMOS active imager at sub-mm-Wave (180GHz) based on a Time-Encoded Digital Regenerative Receiver. He also pioneered the development of self-healing 57-64GHz radio-on-a-chip (DARPA’s HEALICS program) with embedded sensors, actuators and self-diagnosis/curing capabilities; and ultra low phase noise VCO (F.O.M. < -200dBc/Hz) with the invented Digitally Controlled Artificial Dielectric (DiCAD) embedded in CMOS technologies to vary its transmission-line permittivity in real-time (up to 20X) for realizing reconfigurable multiband/mode radios in (sub)-mm-Wave frequencies. He also realized the first CMOS VCO for Terahertz operation (1.3THz) and devised the first tri-color CMOS active imager at 180-500GHz based on a Time-Encoded Digital Regenerative Receiver and the first 3-dimensional SAR imaging radar with sub-centimeter range resolution at 144GHz.
He has founded and co-founded several companies in both US and Taiwan, including a Fabless RF-Chip Design House G-Plus (acquired by SST in 2004 and renamed as SST Communications), and a GaAs HBT Foundry GCTC (merged with Win Semiconductor and became the world’s largest GaAs HBT PA Foundry and went public in Taiwan’s Stock Exchange). He recently spun-off from his UCLA High-Speed Electronics Lab a high data rate (6Gbps) Near-Field-Communication Company (Keyssa), invested by Intel Capital & ALP Venture Capitals.
Dr. Chang has published more than 350 technical papers and 41 US patents in the area of high speed electronic devices and integrated circuits and systems. During his tenure with UCLA, he has graduated more than 35 Ph.D. students and 50 MS students. Dr. Chang is a member of the US National Academy of Engineering and the US National Academy of Inventors, and an Academician of Taiwan's Academia Sinica. He was elected IEEE Fellow in 1996 and received the IEEE David Sarnoff Award in 2006 for the development of HBT power amplifiers leading to their commercialization in wireless communications.
