Show moreIn last 50 years, the feature size of fabrication process for integrated circuits has continuously emerged which proved Moore’s Law that the feature size will decrease in half every 18 months. However, in recent years, the problems caused by highly emerged CMOS devices such as large leakage current, high temperature when operating and high energy consumption became a huge barrier to impede the development of integrated circuits. In 1998, CNFET has been proposed, its great electrical characteristic has attracted a lot of attention and it is the best potential device to replace traditional CMOS devices. Meanwhile, in theoretical area, reversible computing has been proposed to solve the energy dissipation caused by irreversible computing in the system. According to Landauer’s Principle, the power consumption can infinitely approach zero when the circuit is designed based on reversible logic. In this thesis, the author proposed a novel CNFET-based ternary inverter with better performance compared to exist inverters. Also, a Carry Select Adder with improved architecture designed by reversible logic is proposed. M.S. in Electrical Engineering, May 2015 Show less
