A simplified circuit that implements the NOR logic gate, which only outputs ... only the AND and OR gates can be built using diodes only. However, by adding a transistor as an active element ...

NOR, XOR and XNOR gates, as well as a buffer, incorporating light into every logic gate. Traditional inverters – NOT gates – are already made with diodes (typically not light-emitting ...

Examples of logic families are Diode Logic (DL), Resistor Transistor Logic (RTL ... The maximum number of inputs that can be applied to a logic gate is known as fan-in. A 4-input NOR gate can have up ...
