This is the simplest of all the other possible designs of half adder. In the above circuit diagram, it is apparent that one AND gate is used along with EX-OR gate. We will discuss all the possible designing one by one in this article. Half adder can also be designed with the help of universal gates. The circuit of half adder can be designed with the help of basic building blocks of digital electronics realm i.e. We will also discuss other crucial application later in this article. Therefore, it is called half adder.Īlthough, the major significance of adder is that it can perform addition but apart from this it is also used in processors of computer systems for address decoding. The word “HALF” before the adder signifies that the addition performed by the adder will generate the sum bit and carry bit, but this carry from one operation will not be passed for addition to successive bits.
