Carry look ahead Adder: Carry look-ahead adder utilizes the logic gates to look at the lower order bits of augmend and addend to see if a higher order carry is to be generated or not. Carry look-ahead uses the two concepts of carry propagate and carry generate functions. This th adder uses the following equations for i stage: Carry propagate Pi=Ai Bi Carry generate Gi=Ai.Bi Sum Si= Pi Ci Carry Ci+1=Gi+Pi.Ci The circuit diagram of 3-bit Carry Look-Ahead Adder is shown in the following figure:
