Energy Efficient High Performance Adder/Subtractor Circuits

Integrated circuit has been widely used in different applications. The design and development of CMOS transistor provides various advantages such as low power dissipation, cost efficient solutions, enhanced processor performance and size reduction. The main aim of the proposed research work is to increase the performance of the processor and reduce the area by increasing the performance of the adder circuits. The adder circuits enable its availability in many processors. In the processor, ALU is considered as the main functional block for performing any arithmetic operations. A novel high performance adders circuits were designed with the 0.18μm technology in TSMC Spice Simulator. Pass transistor logic has been used to reduce the transistors count in the circuit and hence the performance has increased by 10% when compared with the existing CMOS structure.
