The paper presents new compact static 4-bit CMOS adders based on iterative shared transistor carry lookahead (CLA) units. The CLA units have a regular, fast, simple and multi-output static structure with a small number of transistors. Designs made in 1.0 μm CMOS technology show that these adders reduce the silicon area and improve the timing and dynamic power performance compared with similar static adders
