Abstract:
The last 50 years has been an era where analog equipment has been replaced by digital devices. LP records have been replaced by Compact Discs, NTSC and PAL TV systems have been replaced by digital TVs, VHS video recorders have been replaced by DVD recorders, film cameras have been replaced by digital cameras, and analog wireless communications have been replaced by digital wireless communications. Magnetic recording, optical recording, and signal processing circuitry for wired and wireless networks were replaced from analog to digital. The digitization of these devices and systems was due to the technological shift from bipolar to CMOS and the development of logic and memory circuits supported by scaling laws, but analog-digital mixed integrated circuit technology such as ADCs and DACs was indispensable. Therefore, this talk looks back on the digitization of equipment and the mixed signal integrated circuit technology that contributed to it and will discuss future developments.
Bio:
Akira Matsuzawa received B.S., M.S., and Ph.D. degrees in EE from Tohoku University, Sendai, Japan, in 1976, 1978, and 1997. In 1978, he joined Panasonic and worked on R&D of Mixed Signal LSI technologies; video-rate ADCs and mixed-signal SoCs for DVD systems. In April 2003, he joined Tokyo Tech. as a full professor. He has been studying on millimeter-wave CMOS TRXs and ADCs. He retired from Tokyo Tech. in March 2018 and became professor emeritus and CEO of Tech Idea Co., Ltd.
He received the R&D100 award in 1994, the ISSCC evening panel award in 2003, 2005, 2015, the MEXT science and technology award in 2017, the IEICE achievement award in 2019, and IEEE Donald. O. Pederson award in solid-state circuits in 2022. He is an IEEE Fellow since 2002.
