Overview
Thermal noise gradually becomes a critical issue when the device size reduces to the nano-meter regimes and the power supply of electronic circuits is less than 1 volt. The objective of my research is to build a research program on noise-related issues in semiconductor transistors, to develop techniques to push the sensitivity of noise measurements to new levels, and to use engineering noise expertise to design novel low-noise circuits for sensing, communication, and medical applications. My research work focuses on five noise-related areas, including (1) noise instrumentation, (2) device characterization, (3) noise modeling and low-noise technology, (4) innovated low-noise circuits, and (5) sensor and medical instruments.

In 2015, Dr. Chen was elected as a member of the International Advisory Committee of the International Conference on Noise and Fluctuations, one of the most prominent conferences started in 1968 for research advances in “theoretical and experimental aspects of (electrical) fluctuations across a wide spectrum of scientific and technological fields.”
In 2022, Dr. Chen was invited to serve as an editor of the Journal of Low Power Electronics and Applications.
Dr. Chen’s research work was utilized by many industrial companies such as Conexant Systems Inc., CA; Focus Microwaves, QC, Canada; RF Micro Devices (RFMD) Inc., CA; Rockwell Semiconductor Systems, CA; Siliconlinx Inc., CA; Sony Corporation, Japan; Transilica Inc., CA; and United Microelectronic Corporation (UMC), Taiwan.
Chih-Hung Chen (S’95–M’03–SM’08) was born in Tainan, Taiwan, R.O.C. in 1968. He received the B.Sc. degree in electrical engineering from National Central University, Chungli, Taiwan, R.O.C., in 1991, the M.S. degree in applied science engineering from Simon Fraser University, Burnaby, BC, Canada, in 1997, and the Ph.D. degree in electrical and computer engineering from McMaster University, Hamilton, ON, Canada, in 2002, respectively. In 2002, he joined the Department of Electrical and Computer Engineering, McMaster University, Hamilton, Ontario, Canada, as an Assistant Professor right after his Ph.D. study, and he was promoted to Associate Professor in 2009. He has published about 100 peer-reviewed articles and 19 technical reports. His research interests include the modeling, reliability, and thermal noise characterization of nanoscale transistors and the design of low-noise analog integrated circuits for imaging and sensing systems for medical and environmental applications.
