In our previous discussion, we learned that a common-emitter amplifier is most widely used amplifier circuit and Common Base Amplifier is least widely used amplifier whereas a Common Collector amplifier is moderately used amplifier.

An amplifier is a electronic circuit that increases the strength of a low signal and thus acts as an amplifier. We have covered transistor basics such as what is BJT transistor, Biasing of Transistor, Different Configurations of Transistor in our previous articles. Today in this article we are going to explain working of transistor as an amplifier.
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.
In our previous discussion, we learned that a common-emitter amplifier is most widely used amplifier circuit due to the fact that it provides good current gain and voltage gain, and Common Base Amplifier is least widely used amplifier from all three types of transistor amplifier configurations.
This article is based on the Voltage Multipliers, working of Voltage doubler circuit, voltage Tripler and voltage quadruple and the applications of voltage Multiplier circuits using different waveforms and circuit.
In this article, we will learn about Arduino Microcontroller, Different types of Arduino, Arduino Uno board Configuration, How to Install Arduino IDE and How to Code in Arduino IDE for Building and Learning Basic projects.
Hey in this article, We will solve the mystery behind one of the difficult question “What is Electronics?”, in this article, we will also cover History of Electronics, Difference between Electrical and Electronics, Applications of Electronics, and also fun facts about Electronics.
The first Transistor was invented in 1948 by W.H. Brattain and J. Bardeen; transistor has gained good use, they are used in almost most electronic applications. Though a transistor is only slightly more than 70 years old, and it has replaced old vacuum tubes in almost all applications. In this post, we will cover What is BJT (Bipolar Junction Transistor) Step by Step, we will also learn working of BJT as an Amplifier and Switch and their Applications.
