Akira Matsuzawa’s achievements in integrated circuit design for analog-to-digital converters (ADC) over the past four decades have been critical to the realizations and advancements in digital video equipment and applications. He developed a monolithic video-rate 10-bit ADC that contributed to a digital video switcher for professional digital video systems and HDTV. He developed a parallel interpolation method that led to an optical transmission system for HDTV. His work on a video-rate 10-bit CMOS ADC with capacitive interpolation reduced power consumption and contributed to the development of digital camcorders. He also managed a team that developed a system-on-a-chip for DVD recorder that triggered a remarkable cost reduction and rapid market growth of DVD systems.
An IEEE Fellow, Matsuzawa is a Professor Emeritus with the Tokyo Institute of Technology, Tokyo, Japan, and founder and CEO of Tech Idea Co., Ltd., Kanagawa, Japan.
