Ternary arithmetic and logic unit with carbon nanotube-based field-effect transistors for ultra-low power and high-speed applications

Murali Krishna Peddachowdappa, Vishnu Vardhan


The number of consumers for different applications has expanded tremendously as a result of the growth of consumer electronics-related applications in numerous sectors. Customers often need high-speed applications that use a minimal amount of power for a variety of applications like signal processing, picture processing, communication systems, and so on. The speed of a ternary logic-based design might be greater than that of a binary logic-based one. In this study, a novel architecture for arithmetic and logic units (ALUs) is proposed. The design makes use of ternary logic. In order to accomplish both low power consumption and high performance, methodologies for designing carbon nanotube-based field-effect transistors (CNTFETs) are employed. The method that has been suggested is able to carry out operations such as addition, subtraction, multiplication, reasoning, and comparison. After developing the recommended model, it is compared to earlier designs for power delay product (PDP), average power consumption, and maximum delay duration. The simulation findings show that the carbon nanotube field effect transistors (CNTFET) based ternary ALU circuits outperformed conventional ternary full adder circuits. The suggested design had a delay time of 13.94 ps and a PDP of 5.32 aJ, while the old design had a delay time of 17.67 ps and a PDP of 51.38 aJ.
