Comparative Analysis of CNTFET-Based Standard Quaternary Inverter

Multi-valued logic has more logic states than binary logic operations, which makes it preferable for speed optimization and information handling capacity. Multi-valued logic circuits reduce connectivity complexity, which saves chip area and power usage. This study compares existing quaternary inverter circuits. The ability of CNTFETs to attain the desired threshold voltage by altering the diameter is one of their unique characteristics that is used to design quaternary circuits. Existing standard quaternary inverters are simulated by the Synopsys HSPICE tool using 32nm-CNTFET technology. Existing standard quaternary inverter circuits have been examined for power, delay, and PDP at various temperatures, capacitive loads, and supply voltages.
