Chi‐Wah Kok was born in Hong Kong. He was granted with a PhD degree from the University of Wisconsin–Madison. Since 1992, he has been working with various semiconductor companies, research institutions, and universities, which include AT&T Labs Research, Holmdel, SONY U.S. Research Labs, Stanford University, Hong Kong University of Science and Technology, Hong Kong Polytechnic University, City University of Hong Kong, Lattice Semiconductor, etc. In 2006, he founded Canaan Semiconductor Ltd., a fabless IC company with products in mixed‐signal IC, high performance audio amplifier, and high‐power MOSFETs and IGBTs. Dr. Kok embraces new technologies to meet the fast‐changing market requirements. He has extensively applied signal processing techniques to improve the circuit topologies, designs, and fabrication technologies within Canaan. This includes the application of semidefinite programming to circuit design optimization, abstract algebra in switched capacitor circuit topologies, and nonlinear optimization method to optimize high voltage MOSFET layout and fabrication. He was MPEG (MPEG 4) and JPEG (JPEG 2000) standards committee member. He is the founding editor in chief of the journal Solid State Electronics Letters since 2017. He is also the author of three books by Prentice Hall and Wiley‐IEEE and has written numerous papers on digital signal processing, multimedia signal processing, and CMOS circuits, devices, fabrication process, and reliability.

Wing‐Shan Tam was born in Hong Kong. She received her PhD degree in electronic engineering from the City University of Hong Kong. She has been working in different telecommunication and semiconductor companies since 2004 and is currently the engineering manager of Canaan Semiconductor Ltd., where she works on both advanced CMOS sensor design and high‐power device structure and process development. Dr. Tam has participated in professional services actively, in which she has been the researcher in different universities since 2007. She has been the invited speaker for different talks and seminars in numerous international conferences and renowned universities. She has served as guest editor in several journals published by IEEE and Elsevier. She is the founding editor of the journal Solid State Electronics Letters since 2017. She is the co‐author of another Wiley‐IEEE technology textbook and research papers with award quality. Her research interests include image interpolation algorithm, color enhancement algorithm and mixed‐signal integrated circuit design for data conversion and power management, and device fabrication process and new device structure development.
