This paper presents a new design for penternary logic gates based on carbon nanotube field-effect transistors (CNTFETs). CNTFETs are strong candidates to replace MOSFETs because their threshold voltage can be precisely controlled by adjusting the diameter of the nanotubes.
Multiple-valued logic (MVL), such as ternary, quaternary, and penternary logic, offers advantages over binary logic, including lower circuit complexity, fewer computation steps, and reduced chip area.
We propose two penternary inverter designs operating in multiple-valued voltage mode using CNTFETs. In the first design, resistors are used to implement penternary logic. In the second design, these resistors are replaced with transistors.
Extensive HSPICE simulation results show that both proposed designs significantly reduce power consumption, propagation delay, and sensitivity to process variations compared with existing penternary logic circuits reported in the literature.
