When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Laser diodes work on the same principle as the bigger gas lasers. They function as an optical oscillator by stimulating a chain reaction of photon emission inside a tiny chamber. In edge-emitting ...

Key components in modern technology, laser diodes enable innovations in telecommunications, medical devices, and quantum ...

This Design Idea presents anunusual method of performing theexclusive functions with two resistors,four diodes, and one transistor.The NPN configuration results inthe XNOR operation, and the ...

One of the most exciting device functions, the diode (or rectification) behaviour was first envisioned by Aviram and Ratner 1. The Aviram–Ratner molecular diode consists of a donor and an ...

This ubiquitous diode is an essential component with a simple basic function: It blocks the flow of current in one direction (reverse bias) but allows it in the opposite direction (forward bias).
