Generally speaking, we try to avoid operating diodes in their reverse breakdown region, but Zener diodes are the exception to this rule. Generally speaking, we try to avoid operating diodes in their ...

The lowly diode, a device with only two leads, can nonetheless do many things. Diodes can detect, rectify, suppress, emit light, detect light, change capacitance, emit microwaves and more. This wide ...

How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron than the intrinsic stuff to make ...

A diode is a semiconductor device that exhibits a nonlinear current-voltage relationship. In simpler terms, it allows current to flow more easily in one direction (forward bias) than the other ...

Discover the science behind diodes — the tiny components that control the flow of electricity. Learn how they let current pass in one direction, block it in the other, and power everything from phone ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

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.

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...
