Difference Between Half Adder And Full Adder in Tabular Form

S.No.Basic TermsHalf AdderFull Adder


2.WorkingA combinational logic circuit that performs the addition of two data bits, A and B, is called a half-adder. Addition will result in two output bits; one of which is the sum bit, S, and the other is the carry bit, C.The half-adder does not take the carry bit from its previous stage into account. This carry bit from its previous stage is called carry-in bit. A combinational logic circuit that adds two data bits, A and B, and a carry-in bit, Cin , is called a full-adder.

S =A ⊕ B
C = AB + BC + AC
