In full adder there are three input bits (A, B, C-in). 3 In Half adder there are two input bits ( A, B).

The full adder produces a sum of the three inputs and carry value. Full adder is combinational logical circuit that performs an addition operation on three one-bit binary numbers. The half adder produces a sum of the two inputs. Half Adder Full Adder 1 Half Adder is combinational logic circuit which adds two 1-bit digits. While the output obtained by AND gate is the carry obtained by addition.ĬARRY-OUT = A AND B OR Cin(A XOR B) = A.B + Cin(A ⊕ B)ĭifference between Half adder and full adder : The output carry is designated as C-OUT and the normal output is designated as S which is SUM.Įquation obtained by EX-OR gate is the sum of the binary digits. The first two inputs are A and B and the third input is an input carry as C-IN. Full Adder is the adder which adds three inputs and produces two outputs which consists of two EX-OR gates, two AND gates and one OR gate.
