Universal Ternary Logic Circuit Design Through Carbon Nanotube Technology

The geometry dependant threshold voltage of carbon nanotube FETs (CNFETs), has been often used to design a ternary logic family. However, for the last couple of decades, multiple-valued logic (MVL) such as ternary (base=3) or quaternary (base=4) logic styles has attracted considerable attention. MVL circuits can reduce the number of operations necessary to implement a particular mathematical function and further, have an advantage in terms of reduced area.
