Xnor Gate Circuit Diagram. In which we have used one npn transistor 4 diodes and the resistor between diode bridge and npn is used in series configuration because bjts. An xnor gate sometimes referred to by its extended name exclusive nor gate is a digital logic gate with two or more inputs and one output that performs logical equality the output of an xnor gate is true when all of its inputs are true or when all of its inputs are false if some of its inputs are true and others are false then the output of the xnor gate is false.
If both inputs are low or both are low the output is low. The two input version implements logical equality behaving according to the truth table to the right and hence the gate is sometimes called an equivalence gate a high output 1 results if both of the inputs to the gate are. Schematic of xnor gate using diodes and bjt npn transistor is given below.
Xor which stands for exclusive or and xnor which stands for exclusive nor.

Exnor gate circuit diagram and working explanation the truth table of ex nor gate is show in below figure.
