Abstract
SummaryInternet‐of‐Things (IoTs)‐based embedded systems require energy‐efficient designs for long‐term operation. To achieve energy‐efficient designs, multiple‐valued logic (MVL) circuits and graphene nanoribbon field‐effect transistors (GNRFETs) are used instead of binary logic circuits and complementary metal‐oxide‐semiconductor (CMOS), respectively. This paper presents a novel ultra‐low power and energy‐efficient ternary Half‐Adder (THA) circuit based on unary operators, two power supplies (dual‐VDD), VDD and VDD/2, and two ternary 3:1 multiplexers in 32 nm GNRFET technology. The superiority of the proposed design are improvements between 2.86% and 60% in transistor count, between 86.12% and 97.15% in power consumption, and between 58.14% and 98.39% in power‐delay‐product (PDP) compared to existing THA circuits. Moreover, the proposed THA circuit is also implemented with 32 nm carbon nanotube field‐effect transistors (CNTFETs). Simulation results indicate that the proposed GNRFET‐based THA circuit increases delay by 1.74 × and reduces power/PDP by 89.41%/81.63% compared to its CNTFET‐based counterpart.
