Nanoelectronics and Emerging Technologies
Main research objective is the development, analysis and design of circuits using emerging devices and/or nonconventional logic models, with emphasis on applications with severe constraints on power or energy like IoT. In particular, we explore circuits based on resonant tunel diodes (RTDs), tunel transistors (TFETs and SymFETs) or devices integrating phase transition (Hyper-FETs, VO2). The distinguishing features of these devices is exploited to obtain circuits competitive with respect to their CMOS counterparts in terms of speed, power, energy or area or exhibiting better trade-offs among those criteria. From the logic point of view, we study threshold logic and more recently oscillator-based computing.
