Abstract: Silicon technology used for high-performance digital circuits and it is a dominant technology for making of integrated circuits. But it continuous to scale down the performance of the digital circuits. So for enhancement of digital circuit performance researchers are further investigating other novel materials to introduce into future technology generations. Carbon Nano tubes (CNTs) have significant advantages for the same due to their excellent carrier mobility. The effect of CNTFET parametric variation for chirality (or diameter) with threshold voltage on performance metrics namely delay and power dissipation in the circuit has been analyzed in the present paper. The I-V characteristics of CNTFET for 1.8 voltsof supply voltage have been performed. A comparative study of CMOS and CNTFET logic circuits is carried out. Various logic gates and arithmetic circuits were designed using CNTFETs; their power consumption and delays are obtained and compared with CMOS. It is analyzed that CNTFET based circuits are energy efficient. The circuits have been simulated using HSPICE for 32nm technology node.
Keywords: CNT; CNTFET; Chirality; HSPICE; I-V characteristics; Threshold Voltage.
