AND gate implemented as diode-resistor logic. (Credit: Anthony Francis-Jones) The fun part about logic gates is that there are so many ways to make them, with each approach having its own ...

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computatio… ...

Adding a 9.1v Zener diode from the gate of Q3 to ground will limit the gate voltage if the pushbutton is mashed down or stuck closed. The solution isn’t quite so simple for Q2. Simulating the circuit ...

Consequently, nobody has been able to make reliable diodes, transistors or logic gates out of silicon nanowires. Today, Massimo Mongillo et amis at the Universite Joseph Fourier, Grenoble, in ...
