MOSFET scaling theory primarily attributes for the design of smaller area, optimized power and faster ICs. The scaling theory continued the Moore’s law till the channel size reached the Nano-meter (nm) regime. Further, the scaling of transistors below 45 nm results in more power dissipation due to current leakage. This led in finding alternatives to the traditional CMOS technology. Graphene based FETs (GNRFETs are identified as the potential alternative to the CMOS technology. Graphene Nano Ribbon (GNRFET) based designs are discovered to be the most viable designs considering the performance in terms of power consumption and package area. Design and analysis of CMOS and GNRFET based modified Booth multiplier and modified Wallace tree multipliers are presented in the proposed research work. The performance of CPU mainly depends on the performance of the multipliers in a processing unit. With the scaling of transistors, the advanced devices like finFET, CNTFET and GNRFET based designs promise better solution. 8-bit modified Booth multiplier and modified Wallace-tree multipliers are implemented using CMOS and GNRFET based technologies in the proposed work. The obtained results are analyzed and compared for the key performance parameters like Power Dissipation, Propagation Delay and Power-Delay-Product. The results infer that GNRFET based modified Wallace tree multiplier offers better performance than the other multiplier designs.
