Abstract: The multipliers are the heart of any high-speed computational devices. The multipliers are fully made up of combinational circuits. They have a large circuit design with high gate density, in fact high transistor density. This large active area provides space to have large power dissipation. Obviously, this provides a concern to reduce power dissipation in the multipliers. In this work a high-speed multiplier is designed based on the fast-parallel prefix adder as Kogge stone adder. Different adders are compared with respect to the speed of operation and Kogge stone is the best among the different adders. As Vedic multiplier is considered as the fast multiplier, the adder part in this Vedic multiplier is replaced by Kogge stone adder to form the hybrid high speed Vedic multiplier. This Proposed hybrid Vedic multiplier proved to be efficient in terms of power, delay and Power delay product.
