Am-IDGFET is a new family of particular devices in view of the fact that it associates three benefits: (i) it is usually a 1-D electronic device (CNT or SiNW), meaning high mobility, achievable current density and high I ON /I OFF ratio; (ii) Independently controlled gates which offers the device extra logic options; (iii) ambipolar behaviour opens the way for N- and P-type polarities...
Robotic systems (RSs) are often used for performing critical tasks with little or no human intervention. Such RSs must satisfy certain dependability requirements including reliability, availability, security and safety. In this paper, we focus on the safety aspect and propose a methodology and associated framework for safety assessment of RSs in the early phases of development. The methodology relies...
In this paper, we exploit the ambipolarity property of double gate devices such as DG-CNTFETs to design a new 4:1 multiplexer, with a significant reduction in circuit complexity with respect to conventional CMOS-based multiplexers for equivalent functionality. Based on Pass-Transistor Logic, it demonstrates performance improvement of up to 3× concerning Power-Delay-Product reduction, as compared to...
A novel Ambipolar Binary Decision Diagram (Am-BDD) is proposed in this paper, to adapt this logic synthesis and verification technique to logic built with ambipolar devices. We demonstrate how this method enables us to build DG-CNTFET-based n-input reconfigurable cells based on pass-transistor-logic obtained from Am-BDDs. We also show how specific correlations between configuration signals can lead...
Novel devices based on carbon nanotube field effect transistors demonstrate lower power consumption over conventional CMOS technologies. In this paper, we focus on socalled matrix-based nanocomputer architectures that combine low power and routing overheads of cell matrices with flexibility of FPGAs. We introduce a new interconnect topology for cell matrices that provides the flexible logic depth...
The back-gate terminal on double-gate ambipolar transistors can be used as a powerful vector to achieve fine-grain logic reconfigurability. This paper describes ways of exploiting this property to improve on standard cell logic techniques, and to build logic gates with tunable functionalities. Given the vastly reduced transistor count, conventional use of reconfigurable interconnect at the cell level...
