Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

Diodes are one of the most important parts of any electronics project, and if you don't understand how they work you'll destroy any electronics project you work on. Thankfully, Adafruit has a video ...

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 ...

Frederik Dostal explains the rise of the ideal diode and how it can be used to develop more robust power systems.

The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

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 ...

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 ...
