Transistor as an 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. read more

common Collector amplifier tutorial

Common Collector Amplifier, BJT Transistor Common-Collector Amplifier

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. read more

common base amplifier tutorial

Common Base Amplifier, BJT Transistor Common-Base Amplifier

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. read more

bipolar junction transistor

What is Bipolar Junction Transistor? -Working Principal and Applications

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. read more

Transistor Configurations ,Common Emitter, Base, and Collector Circuits

In this article, we are going to learn about Bipolar Junction Transistor Configurations, Common Emitter, Common Base and Common Collector. So far we have covered Introduction of Bipolar Junction Transistor. read more

Difference between diode and transistor

Difference Between Diode and Transistor, Diode Vs Transistor

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. read more

difference between NPN and PNP transistor

Differences between NPN and PNP Transistor, NPN vs PNP

Before talking about Difference between NPN and PNP Transistor, we must first understand what is NPN transistor and PNP transistor? Basically, NPN and PNP transistors are types of Bipolar Junctions Transistor (BJT), and BJT’s are the electronic component which is widely used for the amplification and switching purposes and in this article, we will learn about the differences between NPN and PNP transistor w.r.t their symbols, construction, operations. read more

Common emitter amplifier

Common Emitter Amplifier, BJT Transistor Common Emitter Amplifier

In our previous discussions, we learned that a transistor can be configured in three different modes, the most widely used transistor configuration is Common-Emitter Configuration, and this is due to the reason, that a common emitter configuration provides good voltage and current gain. read more
