This paper presents a design of ternary arithmetic circuits like half-adder, full-adder and 1-bit comparator using Carbon Nano-Tube field effect transistors. Carbon nano-tube has unique characteristics of behavior according to its arrangement of atoms. Threshold voltage of CNTFETs can vary by changing its diameter and also one intermediate state between two normal stable ON and OFF states introduced for multi-valued logic computation. Moreover ternary logic is a promising alternative to the conventional binary logic design technique, since it is possible to produce three states (FALSE, UNKNOWN, TRUE), and also reduces the number of interconnects and chip area and increases efficiency. In this paper we have proposed novel circuit design of half-adder and comparator based on ternary logic CNTFETs. Increased number of states in CNTFETs will increases the number of bit handling capacity in the device.
