DESIGN OF A CARBON NANOTUBE BASED QUARTERNARY ADDER FOR HIGH SPEED AND LOW POWER APPLICATION

Quarternary logic is the suitable and yet efficient alternate to the binary logic due to its simple design and limited power consumption. The reduction in power consumption is possible because of its narrow circuit overheads. From existing binary circuits, quaternary signals and binary signals are produced through Quaternary(four-valued) logic. The area has been reduced by Quaternary radix on MVL(multi- valued logic). In terms of normalization, short channel effects, impact ionization and surface scattering are among the failures encountered. Resistive-load CNTFET based logic design and a novel Quarternary logic based on CNTFET adder for signal processing application will be designed and compared with existing design. A novel circuit architecture consists of the combination of new device and logic will be proposed. This novel design will be high speed and low power. SPICE simulation is used to verify the proposed design. Comparisons are done with existing design and found an increase in performance of the overall design. In existing work FinFET was done. For implementation Stanford University Nanoelectronics Group CNT model files will be used in Synopsis HSPICE.
