Hey Friends! Hope you are doing great. I am back to give you a daily dose of valuable information so you can always stay ahead of your competitors. I have previously updated the article on NPN transistor that is used for amplification and switching purpose. Today, I am going to unveil the details on the Introduction to PNP Transistor which falls under the category of bipolar junction transistors and comes with three layers i.e. two P-doped layers and one N-doped layer where an N-doped layer exists between two P-doped layers.
Main Function: Small current at one terminal is used to control large current at other terminals.
Major Charge Carriers: Holes
These NPN and PNP transistors come with their own benefits based on the nature of the e ...
Hi Guys! Hope you are doing fine. Today, I am going to give you a detailed Introduction to Transistor. A transistor is a semiconductor device that comes with three terminals, where a small current at one terminal is used to control current at the other terminals. Transistors are mainly used for the amplification of electronic signals. Transistors were first invented by American Physicists John Bardeen in 1947.
Before the inception of transistors, vacuum tubes were used to control the electronic signals. These vacuum tubes come with anode & cathode arrangement and the potential difference across these ends produces the electric current. In the later versions, a filament is added which is used to provide heat to the cathode that directs the electrons towards the anode side. Their complex ...
In a number of applications where speed, latency, and light detection are critical, silicon has reached the limits of its capabilities. Global shipments of silicon between 2021 and 2025 are expected to total 17,600 million square inches, according to Statista. It is clear from this report that Moore's law has the potential to last at least until 2025. However, it is also critical to identify a suitable silicon substitute.
Future iterations of the machine will be able to learn from and adapt to its environment thanks to technologies like artificial intelligence. Because of this, more potent and flexible computational processes are required. It is more probable that the production of chips will usher in a new computing revolution. The following are a few possible silicon chip substitutes th ...
Hello friends, I hope you all are doing great. In our previous lecture, we studied the Basic PN Diode in detail and today, we will discuss a special type of diode called Schottky Diode. This diode was designed by the German physicist Walter H. Schottky, so it's named after him, thus called Schottky.
This diode is mostly used in radio frequency (RF) circuits or in power supplies. So let's get started with the basics of Schottky Diode:
Schottky Diode
Schottky Diode (also called Schottky Barrier Diode or Hot Carrier Diodes), discovered by German physicist Walter H. Schottky, is a special type of diode in which the P-layer(of PN junction) is replaced by the metal layer(i.e. Aluminium, Tungsten, Molybdenum, Platinum, Chromium etc.), while the N layer is of silicon(semiconductor - ...
Hey Guys! Hope you are doing great. Today, I am going to discuss the details on the Introduction to BJT (Bipolar Junction Transistor). It is an electronic component mainly used for amplification and switching purpose. As the name suggests, it is composed of two junctions called emitter-base junction and collector-base junction.
Don't confuse BJT with regular transistors. A transistor is a semiconductor device, comes with three terminals that are used for external connection with electronic circuits. A transistor is termed as a trans resistor which is used as switch or gate for electronic signals. Small signals applied between one pair of its terminals are used to control much larger signals at the other pair of terminals.
Actually, transistors are divided into two categories called u ...
Hello friends, I hope you all are happy, healthy and, content. We have been discussing transistors lately, from the basic definition to the types and characteristics of transistors we have covered it all. If you have a brief idea about transistors, you must be aware of the field effect transistor or you might have heard or read about it somewhere, it is one of the earliest known types of transistors which is our topic of discussion today.
Field Effect Transistors were made to cover up the lacking of previously known transistors which occupied large space and produced a lot of noise, another major problem was the low reliability of previous versions. So, let's get started with the FETs.
Definition of Field Effect Transistor
Let us define field effect transistor first,

Hello friends, I hope this article finds you happy, healthy, and content. Today, we are about to discuss one of the most commonly known types of transistors which you might have heard of many times when reading about transistors, the transistor under study is none other than the “Bipolar Junction Transistor’’, also known as BJT . In this article, we will go through the basics of the bipolar junction transistor including its meaning ,definition, types, characteristics, and applications. So, let's get started.
Definition of BJT
A BJT in its full form is written as bipolar junction transistor and we can define it as,
"A bipolar junction transistor is a three-terminal semiconductor device which is made up of two PN junctions within its structure a ...
Hi Guys! Hope you’re well. In this post today, we’ll cover What is IGBT? We’ll also discuss IGBT Full Form, Pinout, Meaning, Symbol & Working.BJT (bipolar junction transistor) and MOSFETs (metal-oxide-semiconductor field-effect transistor) are commonly used electronic switches that we’ve already studied in detail. These devices are useful when you deal with low-current applications, however, when it comes to high-current applications, these devices don’t work as expected. This is where the IGBT transistor comes in handy. This device is a combination of both BJT and MOSFET and stands fit for high-current applications.
In this post, we’ll cover What is IGBT in detail.
Let’s get started:1. What is IGBT?
IGBT is a three-pin device made of semiconductor material and is used for fast- ...
Hey Guys! I hope everyone's fine. Today, we are going to have a look at What is MOSFET? We will cover MOSFET Definition, Full Form, Symbol, Working & Applications in detail.
MOSFETs are commonly used in many electronic applications. A number of MOSFETs are added in tiny memory chips or microprocessors that are widely used in cell phones and laptops. It is a voltage-controlled device that is used for amplification and switching purposes. I'll try to touch every area related to MOSFET. Let's get started.
What is MOSFET?
MOSFET is an advanced type of FET, manufactured with controlled oxidation of semiconductor, having 4 Terminals, named:

Hello friends, I hope you all are happy, healthy, and, content. Today, our discussion is all about "Diodes". Whoever has been a science student, knows about diodes. Although it seems to be a tiny component of a circuit, apparently it is true but it has a lot of complexities or you can say, it's a storm in a teacup. You might have read a lot about diodes in physics, in today's discussion we would be moving step by step into the pool of diodes from definition to working of diodes, their types, and then lastly its applications. Let's get started!
Diode Definition
First things first, Let's define diode,
A diode is a basic discreet electronic component made up of semiconductor material, used in electronic circuits, which allows unidirectional c ...
