In this paper, we present a carry skip adder (CSKA) structure that has a higher speed compared with the conventional one. The speed enhancement is achieved by applying concatenation and incrementation schemes to improve the efficiency of the conventional CSKA (Conv-CSKA) structure. In addition, instead of utilizing multiplexer logic, the proposed structure makes use of AND-OR-Invert (AOI) and an OR-AND-Invert (OAI) compound gate for the skip logic and Kogge-Stone adder is used in the place of fixed Ripple Carry Adder (RCA). The structure may be realized with fixed stage size style, wherein the latter further improves the speed and energy parameters of the existing adder. Both Existing and Proposed architecture design of CSKAs has been simulated by using Xilinx 14.7. Analysis has been done in terms of speed as well as hardware complexity.
