A Comprehensive Approach for Multi Biometric Recognition Using Sclera Vein and Finger Vein

Abstract: In this work one bit Full Adder with Ten transistors have been proposed. Reducing Power dissipation, supply voltage, leakage currents, area of chip are the most important parameters in today`s VLSI designs. The system reliability can be increased by reducing the cost, weight and physical size and it is achieved by decreasing the transistor count. Therefore the minimum power consumption target and lower area can be meet by reducing the hardware size. Digital circuits can be minimize in two methods. One is human method and another is Computational method. This paper propose one-bit Full Adder based on human method with ten transistors and simulation for the designed circuits were also performed with 4-bit, 16-bit and 32-bit ripple carry adder. Finally the simulation analysis were compared with conventional and proposed Adder in terms of total power consumption, delay, area and power delay product.
