Ling adder

Ling adder

In electronics, an adder is a combinatorial or sequential logic element which computes the n-bit sum of two numbers. The family of Ling adders is a particularly fast adder and is designed using H. Ling's equations and generally implemented in BiCMOS. Samuel Naffziger of Hewlett Packard presented an innovative 64 bit adder in 0.5 mu m CMOS based on Ling's equations at ISSCC 1996. The Naffziger adder's delay was less than 1 nanosecond, or 7 FO4. See Naffzinger's paper below for more details.
