Some logic gates can be produced with just diodes and resistors called diode resistor logic or drl.

Logic gates using diodes. Simulation in this section simulation of the and gate circuit is done using dtl. Circuit of or gate using diode transistor logic is given. So thats the physics behind it in a nutshell.

Logic diodes can perform digital logic functions. Circuit of and gate using diode transistor logic is given. In logic gates logical functions are performed by parallel or series connected switches such as relay contacts or insulated gate fets like cmos controlled by logical inputs or parallel resistors or diodes which are passive components.

App used for simulation is every circuit link is given below. Diode logic was used in early digital computers. With an or gate if 1 or more inputs are high the output is high.

Integrated circuit positive diode transistor logic dtl nand gates ic technology is most properly used for fabricating logic gates. Only if all inputs are low is the output off. If you want to add more inputs you simply add more diodes with the anode independent and the cathode connected to the cathodes of all the other diodes.

Diode logic is implemented by diodes which exhibit low impedance when forward biased and a very high impedance when reverse biased. Diode logic or gate wired or connection if one or both inputs are at logic 1 5 volts the current will flow through one or both diodes. It only finds limited application today.

App used for simulation is every circuit link is given. This current passes through the resistor and causes the appearance of a voltage across its terminals thereby obtaining logic 1 on the output. Working of the circuit in accordance with the truth table is also explained using simulation.

Sometimes it is convenient to fashion a single logic gate from a few diodes. However using ic technology large value resistors 30 k ohms and large value capacitor 100 pf cannot be fabricated economically.
