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 ...

In the first part of this series, we took a look at a “toy” negative-differential-resistance circuit made from two ordinary transistors. Although this circuit allows experimentation with ...

The diode is a fundamental component you must understand if you want to grow your electronics prowess. So today, we’re going to take a quick look at what a diode is, then look at 4½ uses for a diode ...

Members can download this article in PDF format. Power systems employ diodes to perform a variety of functions. For example, diodes can protect against damage due to power-source reverse-polarity ...
