Full Adder Combinational logic circuits - Electronics TutorialFull adder is used to add three bits and produce a SUM and a CARRY outputs. Full adder is mainly needed to add large number of bits. e. g. consider the addition of least significant bit (LSB) of two numbers. Here, the sum under of the LSB is recorded and the carry is forwarded to the next bits. Hence, in order to add the next bits, we need to add three bits with carry from previous addition. Same things happens to other bits until ... The Article Deals About the Full Adder Circuit with the Basic Gates, Truth Table, Equations and the Verilog Code. The Applications are also Discussed. Half and Full Adder are used in combinational circuit design of microprocessor and we explained the truth table, circuit, and K-Map for both Here is the circuit diagram for a full adder using only NAND gates. As you can see the circuit uses 9 NAND gates. And as you may noticed the structure of it is also similar to the previous one.
