New switching devices and circuit design
Clock frequency of microprocessor has reached the point where power is limited by thermal budget for package with recent extremely scaled CMOS transistors, even though microprocessor runs at 0.5V that is almost the lower bound of CMOS LSI. There are efforts on power reduction at various levels from device to system. In this research theme, we would like to focus on circuit design based on more-than-Moore switching devices for low power. Tunnel and negative conductance transistors have been vastly researched at a device level. Design consideration has just started. We would like to contribute to integrated circuits engineering in this area.
We have started with research on an analysis on lower bounds of supply voltages for enhanced-swing Colpitts oscillators, which was presented at IEICE general conference in March of 2018.
