Moreover, power consumption is the main concern for real-time digital systems. In recent times, carbon nanotube field effect transistors (CNTFET) used for arithmetic circuit designs with high performance. A creative substitute for highspeed, less power, and small size in area designs is the CNTFET. This paper presents 1bit full adder with CNTFETs for low power and high performance. Using the computer aided design (CAD) tool the proposed 1-bit full adder design model is simulated using 32 nm with CNTFET technology, a voltage supply of +0.9V. Performance comparisons between various proposed designs and existing 1-bit full adder design have been made in terms of the delay, power, and power delay product (PDP). The proposed CNFET logic also design for n-bit carry look adder (CLA) and compare it to other CLAs to evaluate performance and reliability. The simulation results shows that the proposed adder consume less power than existing adders.
