About Ted Kok

Ted's full name is Chi-Wah Kok, and he was born in HONG KONG, in where he spent his childhood and finally being granted for a Bachelor of Engineering and Master of Philosophy degree in 1990 and 1993 respectively.  He spent all his money and time in the year 1992 to visit various Universities, and participate conferences in US. 

After emptying his wallet, he worked in the semiconductor industry in 1992 to 1995, just to quickly earn enough money for his post-graduate study.  He hoped this helps to explain why and how he can mix semiconductor and digital signal processing in his research portfolio. 

Ted entered the University of Wisconsin Madison in 1995 and defended his PhD thesis in 1997.  After his graduation, he worked with SONY U.S. Research Labs and Stanford University as senior engineer and visiting scholar respectively.  These two interesting places brought him to the multimedia world.  Since then multimedia signal processing became part of his research portfolio. 

In 1999, he joined the Hong Kong University of Science and Technology, and has been happily teaching, working on research problems, interacting with his students, and collaborating with researchers in various parts of the world. He has a very productive tenure in the Hong Kong University of Science and Technology from 1999 to 2006. Up to now, a total of 46 international journal and 141 conference papers have been published, together with 6 Doctoral thesis and 8 Master thesis. His students have been working as professors in the National Chiao Tung University, Taiwan, the Hong Kong University of Science and Technology, Research Fellow in the University of Washington Seattle, and various research and development institutions. He has been an external examiner for graduate students from Universities in Australia, India and Hong Kong. 

He has written three graduate level textbooks published by Prentice Hall in 2008 and 2009. The first textbook "Precoder-Equalizer Systems in Communications" summarized his work in linear precoder with applications in wireless communications. The book has been adopted by a number of senior and graduate level courses in universities in US and Hong Kong. He has conducted seminars in Universities in US, Canada, Taiwan, Korea, Japan and Hong Kong, and tutorial in the IEEE International Symposium on Circuits and Systems 2009. 

The materials included in the second book "CMOS Voltage Reference" integrate the authors' extensive industrial backgrounds in precision voltage reference circuit design fabrication and production, together with their many years of experience in classroom. Studying this text will help the reader to develop a comprehensive understanding of the basic technique of process, voltage and temperrature independent voltage reference circuit design.

The title of the third textbook is "Discrete Cosine Transform: A New Generation". It is written for senior undergraduate and graduate level multimedia signal processing courses. DCT has proved to be very useful in engieering and consumer electronic applications. This book will first review the glorious development of DCT, and then continue to discuss the new development and discoveries of DCT. Those properties are then applied to improve the DCT in various applications, including computational efficiency, coding efficiency and other performance parameters in desire. 

Ted enjoyed the challenges in R&D and the sense of fulfillment when his ideas were finally implemented in consumer goods. In 2006, he founded Canaan Microelectronics Corp. Ltd., a fabless mixed signal consumers' IC design house in Hong Kong. The ICs from Canaan have also been applied in various consumer electronics made by Panasonic, Senario, Vtech, iPlus, Clipsal, Pulse Sonic, etc. just to name a few. Ted embraces new technologies to meet the fast changing market requirements. Since the start-up of Canaan, 2 patents have been filed and licensed to Transpacific IP Ltd. 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 improvement, nonlinear optimization method to optimize high voltage MOSFET layout and fabrication.
