Design of a Low Power CNFET Full Adder Based on XOR/XNOR and Transmission Gates

This paper present a low power design of full adder cell based on carbon nanotube field-effect transistor (CNFETs). Carbon nanotube field effect transistors (CNFETs) are one of the new technologies in promising replacement metal–oxide–semiconductor field-effect transistors (MOSFETs). The main characteristic of the CNFETs is that its threshold voltage can be adjusted by changing the diameter of carbon nonotubes. This design uses XOR/XNOR and transmission gates to generate Sum and Carry. Transistor count for this circuit is 16. This design is simulated using Synopsys HSPICE with 32nm CNFET technology and compared to CNFET full adder cells presented in the past.
