Full Adder Circuit:
A full adder circuit is a digital circuit that performs arithmetic operations on three binary inputs to produce a sum and a carry output.
Inputs and Outputs:
- A full adder circuit has three inputs: A, B, and Cin (carry-in).
- It has two outputs: Sum and Cout (carry-out).
Functionality:
- The full adder circuit adds the three binary inputs (A, B, Cin) to generate a sum output (Sum) and a carry output (Cout).
- The sum output is the XOR of A, B, and Cin inputs, while the carry output is generated based on the majority function of the three inputs.
Truth Table:
- The truth table for a full adder circuit lists all possible combinations of inputs (A, B, Cin) and the corresponding outputs (Sum, Cout).
Example:
- For inputs A=1, B=1, Cin=0, the sum output would be 0 (1 XOR 1 XOR 0 = 0) and the carry output would be 1 (majority of inputs is 1).
Conclusion:
- In conclusion, a full adder circuit has three inputs (A, B, Cin) and two outputs (Sum, Cout), making it a vital component in digital arithmetic operations.

The basic block diagram for a Full Adder is as shown:
A Full adder can be realized using two half adders as shown:
We, therefore, conclude that a full adder combinational circuit has 3 inputs and 2 outputs.
A full adder can be implemented using 2 XOR, 2 AND, 1 OR as shown in figure:
