Design of Multi-Valued Logic circuits utilizing Pseudo N-type Graphene Nanoribbon FETs

Multi-valued logic (MVL) schematics are mainly attractive for nano-scale designs because of various advantages such as large density and faster operation that are harvested utilizing future technologies. This study presents a novel MVL circuits using Graphene Nanoribbon Field Effect Transistors (GNRFETs). The Pseudo N-type GNRFETs are used in proposed circuits for the operation. This technique employs controlling the threshold voltage of P-type and N-type FETs, while ensuring the operation of MVL ternary and quaternary logic designs. Compared to the complementary circuits, the proposed Multi-valued Logic circuits shows improvement in power up to 53.3%, delay up to 36.3% and power delay product (PDP) up to 67.2%.
