The integrated chip technology has revolutionized the world of electronics in which MOS transistors have played a vital role in enhancing performance of integrated devices.
Keywords-FinFET,4-Bit ALU, Adiabatic Logic, ECRL In the implementation of adiabatic logic FinFET based ALU, it is possible to operate at lower operating voltages because FinFET has lower threshold voltages, power consumption is expected to be reduced and speed performance is expected to be improved. For validating the proposed idea we have also designed power gated adiabatic inverter circuits using techniques like ECRL. The four logical operations such as AND, OR, XOR and NOT. The four arithmetic operations include ADD,SUBTRACT and COMPARE. The design of 4-bit ALU, performs three arithmetic and four logical operations. An ALU which acts as core part of CPU is a combinational digital electronic. Now a days ALU is getting more complex and smaller in size to make the development of smaller and most powerful computer systems. In this paper, a novel low-power adiabatic logic based on FinFET devices has been proposed.ALU is the core of all microprocessors. Design and Implementation of 4-Bit ALU for Low-Power using Adiabatic Logic based on FINFETĭepartment of Electronics and Communication, Bangalore Institute of Technology,Ībstract – With the aggressive scaling of device technology, the leakage power has become the main part of power consumption, which seriously reduces the energy recovery efficiency of adiabatic logic.
