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 ...

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 ...

A diode is a tiny component with a powerful job—controlling the direction of electrical current. This video explains how ...

This video explains the function of diodes and how they are used to control the flow of electrical current in electronic circuits. Diodes are essential components that allow current to move in only ...

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 ...

Nearly four decades ago (in his Designs for High Performance Voltage-to-Frequency Converters), famed designer Jim Williams cataloged five fundamental techniques for voltage to frequency conversion.
