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 ...
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,
"The Field e ...
Hello Friends, I hope you’re well today. Today, we are going to start a new tutorial series on Semiconductors. In this series, we will discuss the semiconductor components, devices, etc. in detail. We will start from the very basics and will gradually move towards complex concepts. As today's our first tutorial in this series, we will discuss the basics of semiconductors. So, let's get started:
What is a Semiconductor?
A Semiconductor Material is defined by its ability to conduct electricity and its conductive
properties lie between conductor and insulator, normally ranging between 10-6 to 10-4 (Ωm)-1.Under specific conditions, Semiconductors have the ability to act either as a pure conductor or a pure insulator.Examples of Semiconductor materials
are Silicon, Germanium, Gallium A ...
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 ...
Hello, Students here I am present to cover an article on a series of Electronic devices and circuit theory. The foremost article of this series is Ideal diode vs practical diode. I try to elaborate on basic to modern theory related to the diode. This component act as fundamental to many important circuit devices such as rectifiers, transformers, etc. The question which we cover in this article are;
What is a diode?
How a diode is formed? Which methodology manufacturer utilized while the formation of the diode?
What is the concept of doping and PN junction in diode theory?
How does a Diode work?
What type of biasing allows a diode to conduct? Under which situation of biasing diode offers a restriction while conducting?
Upon which cha ...
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 - ...
Hello Guys! I hope you are doing great and having fun. I am back to give you a daily dose of knowledge that will enhance your learning skills and put you ahead of others. Today, I am going to give you details on the Introduction to JFET. It is a Junction Field Effect Transistor that consists of three terminals named drain, source and gate. It comes in two configurations called the P-Type channel and the N-Type channel. I'll give you brief details on JFET and try to cover as many aspects as possible. Let's get started:
Introduction to JFET
JFET (Junction Field Effect Transistor) is a uni-polar voltage-controlled device that consists of three terminals called drain, source and gate.
Unlike bipolar junction transistors which are bipolar current-controlled devices in which a small amo ...
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 ...
Hey Guys! I hope you all are doing great. In the previous tutorial, we studied the basics of Semiconductors, where we briefly discussed the PN Junction. Today, we are going to have a detailed overview of PN Junction.
But before getting into the details of PN Junction, we need to first recall a few concepts from the previous lecture:
Semiconductor Basics
As we know, the conductive power of a semiconductor material lies between a conductor and an insulator. So, it can act as a pure conductor as well as a pure insulator, depending on the applied conditions. Semiconductors are divided into two types:
Intrinsic Semiconductor.
Extrinsic Semiconductor.
Intrinsic Semiconductor
A semiconductor in its pure form is called an Intrinsic semiconductor. In this state, the outermost valan ...
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 ...
