A model to explore the scaling limits of electrostatically actuated nanorelays is presented, which shows that adhesion in a nanorelay's contact interface limits its performance with respect to operating voltage, contact resistance, and switching energy. For logic applications, we show that an ultimately scaled relay can be more efficient than conventional metal–oxide–semiconductor devices if <formularef...
Ultra wideband (UWB) wireless positioning systems are robust for use in indoor environments where multipath is a factor. Indoor hospital environments including the operating room provide a challenging medium for wireless propagation. Medical applications for UWB positioning include tracking people and assets as well as computer assisted surgery. Our UWB positioning system can achieve real-time 3-D...
A detailed circuit assessment of Tunneling Field Effect Transistors (TFET) versus MOSFET transistors operating at a supply voltage near device threshold is reported, including the consideration of P-TFET device design. 20nm gate-length InAs TFET and Si MOSFET device characteristics are simulated and used in circuit simulations. For ultra low power logic applications, TFET logic can operate at equal...
