FINFET BASED 16 BIT ALU UNITS FOR LEAKAGE REDUCTION

Chandrakant J., D. Ane Delphin

Abstract: An Arithmetic Logic Unit (ALU) acts as a heart for all microprocessors. It performs logical or arithmetic operations. It’s getting smaller and more complicated in recent days to enable the progress of extra powerful however smaller design. However, there are just a few limiting reasons that slow down the growth of smaller and additional problematic chip when CMOS is used. The foremost boundaries in scaling the bulk CMOS are quick channel effects, sub-threshold leakage and gate-dielectric leakage. FinFET has an excellent control on short channel results within the sub-micron regime hence developing the probability to scale the transistor. Because of this cause, the small size transistor can have a higher intrinsic gain and less off-state current in comparison with the bulk counterpart. 16-bit ALU that performs basic logical, arithmetic, and shifting operations has been designed using FinFET constructions and leakage power has been studied and compared with the MOSFET structure.
