A Novel High-speed Adder-Subtractor Design based on CNFET

Carbon Nanotube filed-effect transistor (CNFET) is one of the promising alternatives to the MOS transistors. The geometrydependent threshold voltage is one of the CNFET characteristics, which is used in the proposed design. In this paper, we present a novel high speed Adder-subtractor cell using CNFETs based on XOR gates and multiplexer. Presented design uses fourteen transistors, ten for full ...

A High-Speed Dual-Bit Parallel Adder based on Carbon Nanotube ‎FET technology for use in arithmetic units

In this paper, a Dual-Bit Parallel Adder (DBPA) based on minority function using Carbon-Nanotube Field-Effect Transistor (CNFET) is proposed. The possibility of having several threshold voltage (Vt) levels by CNFETs leading to wide use of them in designing of digital circuits. The main goal of designing proposed DBPA is to reduce critical path delay in adder circuits. The proposed design positi...
