Implementation of Full Adder using NAND Gates
Why is NAND Gate known as Universal Gate?
NAND Gate is known as Universal Gate because it produces basic logic gates like AND gate, OR gate, and NOT gate in the absence of any other gates.
What is the Expression for Sum in Full Adder?
The expression for Sum in Full Adder is:
S = A ⊕ B ⊕ Cin
What is the Expression for Cout in Full Adder?
The expression for Carry, Cout in Full Adder is:
Cout = AB + (A ⊕ B).Cin
How many NAND gates are required to achieve Full Adder?
To implement full adder using NAND gates we require nine NAND gates.
How is a NAND gate unlike from an AND gate?
The inverse output of an AND gate is the NAND gate which means that the output of an AND gate will just be opposite in case of NAND gate. It is short form of NOT-AND gate.
Implementation of Full Adder using NAND Gates
In Digital Logic Circuit, Full Adder is a Digital Logic Circuit that can add three inputs and give two outputs. The three inputs such as A, B, and input carry as Cin. The output carry is represented as Cout and the normal output is represented as S, Sum. The Cout is also known as the majority 1’s detector, whose output goes high when more than one input is high.
In Digital Logic Circuits, Full Adders are implemented using digital logic gates such as OR gate, AND gate, NOT gate, NAND gates, NOR gates, etc. In this article, we will explore Full Adders, and NAND Gates and execute the Implementation of Full Adder using NAND Gates.
