A PN junction is said to be forward biased when the externally applied voltage is in such a direction that it cancels the potential barrier of a diode, hence, allowing the current flow.

In this article, we learn about Biasing of PN Junction in detail – like how to bias a PN junction Diode (Forward & Reverse bias methods), the behavior of PN junction during forward & reverse bias, how to plot the Voltage-Current characteristics, and many other essential concepts regarding a PN junction diode. So let’s begin.
Gunn Diodes are named after a researcher J. B. Gunn from an IBM, he discovered that the materials form group (III-V) of predict table such as Gallium arsenide (GaAs), and Indium Phosphide (InP), when applied voltage increases up to the certain value the mobility of electrons in these materials decreases, thereby producing negative differential resistance region. A diode made up of these materials can generate microwaves frequencies.

This new article is based on the PhotoDiode? Working, Operations, and Applications.
Difference Between Diode and Transistor
Difference between Diode and Transistor is very important to understand because diode and transistor are considered as the heart of the electronic circuit. The major difference between diode and transistor is that a diode is a current controlling device which allows the current in only one direction it has two terminals and it is mostly used for converting AC into pulsating DC.
Clipper and Clamper Circuits are different with respect to their operation, circuit diagrams, and their applications and in this article we, will cover Difference Between Clipper and Clamper w.r.t their Circuits, Operations, and their Applications.
