Not Gate Circuit Diagram Using Diode. Presently we will learn how to implement the or gate using drl diode resistance logic. With diode logic it is also difficult to build any gates other than and and or.
A not gate can easily be realized by using a simple bipolar transistor. This diagram shows how to make a simple dtl circuit that has the same function as a nor gate. This voltage drop cannot be recovered using just passive circuits so this severely limits the number of gates that can be cascaded.
In the diode logic and gate when the input a 5v and input b is also 5v in this case both diodes d1 and d2 are off because of reverse mode.
The truth table of a not gate can be represented as. If it made by using diodes then it called dl diode logic and if using transistors it called rtl resistor transistor logic. Other logic gates include and gates or gates nand gates nor gates xor gates xnor gates. This diagram shows how to make a simple dtl circuit that has the same function as a nor gate.
