Full Adder
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A full adder is a digital circuit that adds three binary bits (two significant bits and a carry-in) to produce a sum and a carry-out. It is a fundamental building block for arithmetic logic units.
Example in context
“In digital design, a full adder adds three bits and produces a sum and a carry output.”
“Dijital tasarımda, tam toplayıcı üç biti toplar ve bir toplam ve elde çıkışı üretir.”
Where engineers use it
Used in arithmetic circuits of CPUs and ALUs to perform binary addition. Engineers design with full adders to build ripple-carry and carry-lookahead adders. Understanding propagation delay is critical.
Synonyms: FA
Antonyms: half adder
Practice: can you use “Full Adder” at work?
You are designing a 4-bit ripple-carry adder and need to compute the worst-case delay. Explain how the full adder's carry propagation affects overall timing.
Show a model answer
“The propagation delay of the full adder must be minimized for high-speed design.”
