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 ...
Hi Guys! Hope you are doing great. Today, we will have a look at an electronic component named Diode. We will discuss Diode working, Symbol, Applications and characteristics in detail.
A diode is an electronic component, that allows the flow of current in one direction only. It exhibits low resistance in one direction and very high resistance in the opposite direction. 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.
Diodes are normally used in rectifiers, where they convert AC signals to DC signals. They come with a wide range of applications including power conversion, radio modulation, l ...
Hello Friends! I hope you are well. Today, I am going to give you a detailed Introduction to NPN transistor. In this tutorial, we'll look at the NPN transistor, how it works, circuit diagram, output characteristics curve, and applications. It is a bipolar junction transistor mainly used for current amplification and switching purposes.
BJTs (Bipolar Junction Transistor) are divided into two types i.e. NPN transistor and PNP transistor. Both transistors are different in terms of their electrical composition and construction, however, both are used for amplification and switching purposes in one way or the other.
What is NPN Transistor?
NPN transistor is a bipolar junction transistor(BJT), composed of 3 semiconductor layers in a way that o ...
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 ...

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?

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 ...
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 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?

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 - ...
