Xnor Gate Circuit Diagram Using Transistor. 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 operates on input current not input voltages. When the voltages at terminals a and b are at opposite logic states forward biases the emitter base junction and turns on the transistor.
When b input is high left nmos transistor is on and the logic value of a is copied to the output f which satisfies. 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 operates on input current not input voltages. The realization of and gates is also done by using transistors and the diodes.
The realization of and gates is also done by using transistors and the diodes.
Construction and working mechanism of xnor gate xnor gate using bjt and diodes. Thus an approximate logic high voltage v h 0 6v v ce is available at output terminal y. The realization of and gates is also done by using transistors and the diodes. What you need a breadboard a bunch of 5k and 10k resistors and transistors a led you can use any npn type transistor for example 2n3904 bc547 bc548 bc549 etc these are basic circuits so they can be improved with diodes for reverse voltage protection for example or can be simplified xor xnor gates.
