A Systematic Review on Various Types of Full Adders

Abstract

In recent years, Personal computers (PCS) and mobile phones (MP) are more used in the world but still now very fewer researchers focus to structure the low power (LPW) and high speed (HS) Multiplier (MUL) and accumulate unit (MACU). MACU is a main arithmetic component in PCS and MP for doing any math work. In MACU main components are MUL and adders and also adder is one main component in MUL unit. So, in this paper mention recent XOR-XNOR based adders and also mention techniques for optimizing the performance constraints. This thorough investigation incorporates the deliberate improvement, looks at the most recent design of each adder, and advocated what one is better over other revealed viper is likewise featured.
