Performance Evaluation of CNTFET Based Ternary Basic Gates and Half Adder

The shrinkage in size of VLSI chips as well as improved energy efficiency is the need of the modern digital era. Using ternary logic instead of conventional binary logic helps to reduce circuit complexity and hence reduces chip area. Carbon nanotubes FET (CNTFET) are preferred over CMOS for logic design due to its high performance i. e. excellent transport property, low resistivity and higher current on-off ratio. The performance of ternary based logic gates is evaluated in terms of parameter such as power dissipation and delay.
