What is an LED but a diode, and it’s well known that diodes also have capacitance. In fact, this quality is exploited in varactor diodes, a specialty diode whose capacitance can be changed by ...

A simplified diode switch in the reverse biased Off position. To illustrate a basic diode switch, we’ve prepared a couple of simplified circuit diagrams. The first shows the anode tied to ground ...

The main emphasis is on the fundamental physics behind device operation. Topics include the background physics and the basic principles of electronic device operation with emphasis on bipolar ...

Fermi vs. Bose statistics, Quantum solution to the particle-in-the-box potential, and Basics of a semiconductor. In this module, you will learn the fundamental operating principles, design, ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...
