Adders are one of the widely used digital components in digital integrated circuit design. Addition is the basic operation used in almost all computational systems. Therefore, the efficient implementation and design of arithmetic units requires the binary adder structures to be implemented in an equally efficient manner. A ripple carry adder has smaller area but less speed. A carry look-ahead adder is faster though its area requirements are high. Carry SeLect Adders (CSLAs) lie in middle. In this paper, a novel carry select adder using Binary Excess Converter (BEC) is proposed.
