A Novel Energy-Efficient Ternary Successor and Predecessor Using CNTFET

This paper presents a novel design for a ternary successor and predecessor using carbon nanotube field-effect transistors (CNTFETs). The chirality of the CNTFETs is utilized for threshold voltage control. The proposed designs are simulated and examined, using Synopsys HSPICE with Standard 32 nm CNTFET technology in various situations. Simulation results demonstrate the correct and high-performance operation of the proposed circuits even in the presence of process variations. It is shown that the proposed ternary circuits achieve a significant saving in energy consumption (95.18 % for successor and 91 % for predecessor) compared with previously presented designs.
