M. C. Frank Chang

Director: Prof. Mau Chung Frank Chang

Dr. M.-C. Frank Chang is the Wintek Chair in Electrical Engineering and Distinguished Professor of UCLA. (1997-present) Throughout his career, he has focused on the research & development of high-speed semiconductor devices including heterojunction bipolar transistors and CMOS integrated circuits for radio, radar, RF-interconnect, spectrometer, and AIoT System-on-Chip applications from microwave to Terahertz frequencies. He is a Member of the National Academy of Engineering, European Academy of Sciences and Arts, a Fellow of the National Academy of Inventors, and an academician of Academia Sinica, Taiwan. In addition to receiving the prestigious AAES John Fritz Medal (2025), he was also recognized by the IEEE David Sarnoff Award (2006), IET J.J. Thomson Medal for Electronics (2017), and IEEE/RSE (Royal Society of Edinburgh) James Clerk Maxwell Medal (2023) for his landmark contributions to modern high-speed electronics with unprecedented functionality, bandwidth, efficiency and re-configurability. He also served as the President of the National Chiao Tung University, HsinChu, Taiwan (2015-2019).

 Modern mobile systems rely on sophisticated digital modulation schemes to achieve effective use of frequency bandwidth for high data rate throughput. These systems, including all smartphone transmitters, cannot be deployed without using high efficiency/linearity/reliable power amplifiers, which are primarily made of GaAs HBT/BiFET. In 2021 alone, more than 1.4 billion smartphones are shipped (https://www.statista.com). Super-majority of these smartphones used GaAs HBT/BiFET for power amplification to meet the required linearity and efficiency. For the past 30 years, >30 billion smartphones were shipped, with total production of GaAs HBT/BiFET PAs exceeding 100 billion units, because each smartphone may support Quad-band GSM/EDGE and WCDMA Band I/II/V/VIII and LTE plus 5G Sub-6GHz bands. GaAs HBT/BiFET PAs pioneered by Chang’s Rockwell research team (1983-1997) and its later spin-off commercial entities including Skyworks Solutions have grown into a globally dominant business for 2/3/4/5G smartphone insertions for the past three decades.

Prof. M.C. Frank Chang joined UCLA in 1997 and quickly broadened his research spectra from high-speed semiconductor technologies to ultra-high-frequency circuit and systems, especially to digitally re-configurable (or software-defined) ICs and Systems-on-Chip (SoC) for (sub)-mm-Wave radio, radar, interconnect, edge-computation and instrumentations (spectrometers & imagers). His invented DiCAD, which is radically different from that of original un-tunable AD (W.E. Kock, “Metallic Delay Lenses”, 1948, B.S.T.J.), has been widely used by micro-/mm-Wave circuit designers to realize broad or multi-band resonant-tanks, antennas, filters, inductors/transformers, phase/amp shifters etc. for (sub_mm-Wave systems. For instance, DiCAD-PLLs have been used to realize US DARPA’s HEALICs Self-Healing Radio-on-Chip (57-64GHz), and NASA’s C-MLS & ASTHROS Radiometer & Spectrometer SoC (183/540-660GHz) with orders-of-magnitude size/weight/power reductions for planetary (Global Warming) and Astrophysics (Stellar Feedback near TW Hydrae) explorations. The DiCAD-PLL also facilitated his invented multiband RF-Interconnect for near-field contactless connectivity (6Gbps at 57-64GHz) to enable Acer’s 360-Spin Laptop and LG-V50 two-screen Smartphones by his spin-off company Keyssa. He also pioneered the use of RF-Interconnect via hollow plastic waveguide for ultra-wide band and energy-efficient (<1pJ/bit/m) inter/intra-Rack communication in AI data centers. More recently, he co-founded another spin-off company Kneron, by using his invented RCNN Accelerator, for state-of-the-art edge-AI inference computing. It has won many academic and industry recognitions, including IEEE 2021 Darlington Best Paper Award, EE Times’ Al Top 10 Awards ’19, ’20, ’21, consecutively, and EE IoT Times’ Edge-Al Top 3 Award along with Intel and TI.

Dr. Chang’s research has created new methodologies to design/fabricate reliable heterojunction devices, new device/circuit (DiCAD) and algorithms to sense/transmit/receive/compute data with unprecedented re-configurability, bandwidth and resolution for SWaP-efficient system insertions.

 

Early Life and Education:

 Frank Chang was born in Taichung, Taiwan in 1951. and Frank’s father and mother had just crossed over from the mainland following the end of the Chinese Civil War. The densely populated and heavily polluted city air was no match for Lien-Bih Kuo, Frank’s mother, and the family relocated to a small mountain village when Frank was just 4 years old. He was the eldest of three brothers. There was limited activity in the small village called Chushan (i.e. Bamboo Mountain), and Der-Chan Chang, Frank’s father, who worked as a local high school teacher, encouraged him to read and study according to his own interest. At 14, Frank, along with other top students at his local grade school, were admitted to the best high school in Taichung. Frank lived first with relatives and later with his village friends and did extremely well in the classroom, particularly on physics and chemistry. He did so well on his early exams that his teachers thought he was being tutored on the side, but he was just very determined to succeed. He was later admitted to National Taiwan University (NTU) to earn his B.S. in Physics (1968-1972), his M.S. in materials science from National Tsinghua University (1972-1974), and his Ph.D. in Electronics from National Chiao Tung University (1974-1979). He married LinFong Shelly Chang (an NTU schoolmate) in 1975 and immigrated to US in 1979 and they bear a son Albert (Chi-Jun) Chang and a daughter Pearl (Chi-Yu) Chang.
