Prof. Mau-Chung Frank Chang
Dr. M.-C. Frank Chang is the Wintek Chair in Electrical Engineering and Distinguished Professor
at University of California, Los Angeles. Prior to joining UCLA, Dr. Chang was the Assistant Director and Department Manager of the High Speed Electronics Laboratory of Rockwell International Science Center (1983-1997), Thousand Oaks, California. In this tenure, he developed and transferred the AlGaAs/GaAs & InGaP/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 Solutions). 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 thirty 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 radio, radar, imager, spectrometer and interconnect System-On-Chip (SOC) 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 CMOS active/passive imagers, respectively, at mm-Wave (100-200GHz) frequencies. 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 for enhanced performance yield to counter process variations and aging effects; and ultra low phase noise VCO (F.O.M. less than -200dBc/Hz) with his 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 frequency bands. He also realized the first CMOS Frequency Synthesizer for Terahertz operation (PLL at 560GHz) 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. More recently, he has led students to invent a Reconfigurable Convolution Neuron Network (RCNN) Accelerator for AIoT applications and been recognized by IEEE's 2021 Darlington Best Paper Award.
He has founded / co-founded several companies in the 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). More recently, He has spun-off a prize-winning edge-AI solution provider company (Kneron) from his UCLA High Speed Electronics Lab, and won global competitions/recognitions from 2018 EE Times AI/60, 2020 AI's Artificial Intelligence Excellence, 2020 CBINSIGHT's AI/100, and 2021 EE Times Silicon/100 Awards.
Dr. Chang has published more than 460 peer-reviewed technical papers and 58 US patents in the area of high speed and high frequency semiconductor devices and integrated circuits (SoCs) for radio, radar, imager, spectrometer, interconnect and AIoT CNN accelerators. During his tenure with UCLA, he has graduated more than 50 PhD students and 90 MS students. Dr. Chang received his BS in Physics from National Taiwan University (1972), MS in Materials Science from National Tsing Hua University (1974), and PhD in Electronics Engineering from National Chiao Tung University (1979).
