Abstract — Reversible logic is one of the most important issue at present time and it has different areas for its application. The main purposes of designing reversible logic are to decrease quantum cost, depth of the circuits and the number of garbage outputs This paper represents an another approach to realize 4 bit 2’s complement adder subtractor by using reversible logic gates like Feynman Gate, DKG gate and one control line. A also a new reversible gate DKFG is proposed. Keywords—Reversible logic, Basic Reversible Gates, 2’s Complement, Reversible full adder, Reversible full sub-
