Abstract

A fully static complementary metal-oxide semiconductor (CMOS) implementation of a Ling-type 32-bit adder is described. The implementation saves up to one gate delay and always reduces the number of serial transistors in the worst-case critical path over the conventional carry look-ahead (CLA) approach with a negligible increaser in hardware.
