I. Introduction
In the recent years, with the heavy demand of advanced technology, the designers are working within limited leakage powers specifications to get larger battery life. The designs of these products not only require light weight and slim size, but also low power consumption and fast production to fill up market needs. Almost all battery functioned gadgets like mobile, laptop, tablet, personal digital assistants (PDAs) and ultra-large-scale integration, etc. are designed with better PDP that simultaneously provides assistance to other factor such as chip area, consumption of power, speed of operation, regularity of circuit and long battery life that demand in VLSI [1], [2].
