by Anthony Smith @ edn.com: Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots in series to give coarse/fine control (or using a multiturn pot) would offer improved control over the varactor voltage. However, […]

In this article we will discuss about the various types of diodes, their working principle and their common uses. We will cover many common diode types, such as P-N junction diode, Zener diode, Schottky diode, LED and laser diodes, photo diode, varactor diode, avalanche diode, PIN diode etc. Feel free to leave a comment with […]
