JCS_V2_N4_RP1 Shalini Sampath P. Journal on Communication Engineering and Systems 2277-5242 2 4 1 6 Residue Number System (RNS), Booth Multipliers, Parallel Prefix Adders (2^n) -1 is one of the commonly used moduli in Residue Number Systems. In this paper the power analysis on Radix-4 8-bit modified booth multiplier is made considering different parallel prefix adder structures. The technology used for the design of multiplier is 0.35μm CMOS technology. The parallel prefix adder structures that are included for the analysis are Kogge Stone adder, Brent Kung adder, Ladner Fischer adder etc. The analysis is made based on the power consumption made by the circuit and the total number of components (in terms of basic gates includes AND, OR and NOT) used for the design. It is found that multiplier structure with Ladner Fischer adder turn out to provide a better design with reduced power and basic gates required compared to other multiplier designs.
