<p><b>Abstract</b>—In this paper, we present new design methods for modulo 2<SUP>n</SUP>± 1 adders. We use the same select-prefix addition block for both modulo 2<SUP>n</SUP> - 1 and diminished-one modulo 2^n+1 adder design. VLSI implementations of the proposed adders in static CMOS show that they achieve an attractive combination of speed and area costs.</p>
