Low-power analog circuit design becomes crucial for IoT era. Many sensors will be distributed everywhere and communicate each other in wireless method. Power consumption becomes serious issue for small battery, weak energy harvesting, small form factor, and long life operation. This talk will review and discuss the current status of low-power analog circuit design and recent methods to reduce the power consumption of data converter that is the most important core analog circuit. In particular, the dynamic analog circuit with capacitive operation will be discussed in depth to explain the dramatic power reduction of ADC, 1/1000 during recent 12 years.  Furthermore, the future technology direction involving full-automated analog circuit design technique will be discussed to address the serious lack of analog engineers and to shorten the design time. 




Akira Matsuzawa received B.S., M.S., and Ph. D. degrees in electronics engineering from Tohoku University, Sendai, Japan, in 1976, 1978, and 1997 respectively. In 1978, he joined Matsushita Electric Industrial Co., Ltd (Panasonic). Since then, he has been working on research and development of analog and Mixed Signal LSI technologies; ultra-high speed ADCs, intelligent CMOS sensors, RF CMOS circuits, and digital read-channel technologies for DVD systems. From 1997 to 2003, he was a general manager in advanced LSI technology development center. On April 2003, he joined Tokyo Institute of Technology and he is professor on physical electronics. Currently he is researching in mixed signal technologies; RF CMOS circuit design for SDR and high speed data converters. He served the guest editor in chief for special issue on analog LSI technology of IEICE transactions on electronics in 1992, 1997, and 2003, the Vice-Program Chairman for International Conference on Solid State Devices and Materials (SSDM) in 1999 and 2000, the guest editor for special issues of IEEE Transactions on Electron Devices, the committee member for analog technology in ISSCC, the educational session chair of A-SSCC, the executive committee member of VLSI symposia, the IEEE SSCS elected Adcom, the IEEE SSCS Distinguished lecturer, the chapter chair of IEEE SSCS Japan Chapter, and the vice president of Japan Institution of Electronics Packaging. He received the IR100 award in 1983, the R&D100 award and the remarkable invention award in 1994, and the ISSCC evening panel award in 2003, 2005, 2015. He is an IEEE Fellow since 2002, and an IEICE Fellow since 2010.
