In the last post, we had seen Ac analysis of JFET and there we had completed the whole JFET. Until now we had studied all the concepts of BJT and JFET in great depth. Now from this post, we will be starting with MOSFET. The full form of MOSFET is M etal O xide S emiconductor F ield E ffect T ransistors. In the end, it will be very much clear to you, why it is called metal-oxide field-effect transistors. 1) Types of MOSFET :- There is a total of 2 types of MOSFET i.e. Depletion-MOSFET (D-MOSFET) and Enhancement-MOSFET (E-MOSFET). Further, both are divided into 2 i.e. N-type and P-type. While explaining the construction part of MOSFET you will understand these 2 types of MOSFET in great depth but for now, just remember the symbol of both the MOSFET. Symbol :- NOTE :- MOSFET can be a 3 terminal device or 4 terminal device. Sometimes substrate is shorted with the source internally at that time we can say that it is a 3 terminal device if the substrate is not connected with the source inter...

Until now we had covered almost all of the topics of dc analysis of JFET . If you want to start with Dc analysis of JFET, I recommend you start with this post on JFET:- Junction Field Effect Transistor .  So in this post, we are going to study ac analysis of JFET. Before starting with the post I want to give you a brief idea that what concepts we are going to learn by the end of this post.  1) Ac Analysis of CS-amplifier 2) Ac Analysis of CG-amplifier 3) Different parameters and it's importance while designing an amplifier.  We will try to understand it's working by using bypass and unbypassed capacitors. 1) Ac Analysis of CS Amplifier:- Here I'm considering a self-bias circuit you can also consider voltage divider bias and according to the superposition theorem during ac analysis, all the dc sources are grounded. (Remember that during Ac-analysis capacitors are replaced by short-circuit and during Dc-analysis capacitors are replaced by open-circuit.) a) Calculation of ...

In the last post, we studied different biasing techniques of JFET and we also saw some parameters and their importance while in the end, we concluded that self-bias and voltage divider bias circuit gives the best result while explaining those techniques

In the last post, we saw the different operating region of JFET , in this post, we are going to learn different biasing techniques of JFET. I hope you read the earlier post. So let's start with this post

In the last post, we studied the difference between JFET and BJT there I had explained why we prefer JFET over BJT. I hope you understood all the concepts of JFET which we had studied up till now.

In the last post, we studied about characteristics and configurations of JFET in great depth. Now in this post, we are going to analyze the key differences between BJT and JFET.

In the last post of Jfet, we learned some basic concepts of Jfet . In this post, we will be learning the configurations and characteristics of Jfet.

As a part of our ICCD project, we had designed automated hearing aids. I hope that many of you had

We had finished learning all the concepts of Bjt from basics and in the end, we had designed an amplifier using BJT . From this post, we will start learning about new transistors i.e. JFET.

Until now we have seen the h-model of BJT and based on that we had designed an amplifier . Now we are going to see the r π  model of BJT in depth.

In my last post, I explained to you why we are using voltage divider bias and some formulas to design an amplifier so in this post I will show you how to design a basic amplifier.

I was very much impressed by the idea of sir Elon Musk he belives in using renewable energy rather than using conventional energy because of this thinking he proposed the idea of the TESLA

In the last post, we studied the transistor model for small-signal analysis, and there I had briefly explained that why we are using h-parameter for the analysis of the BJT transistor .

First of all, we have to understand what is a two-port network to understand the transistor as a 2-port network. Two-port Network :- Any network with 4 nodes or 4 terminals is considered as a two-port network only if it satisfies the port condition  Port Condition :- If current entering from one terminal is leaving from some other terminal with the opposite direction but with equal magnitude then these two terminals combine to form a single port. So for a two-port network, we require 4 such terminals that satisfy the port condition. As you can see above the transistor obeys port condition and therefore we can say that the transistor is like a two-port network. There are total of 6 parameters for a two-port network but for analysis of the transistor, we will be dealing with only one parameter that is an h-parameter. You can also go with g-parameter  Since,  h=1/g Now the question arises why we are only using the h-parameter for the analysis of transistors?  So here is...

I was very much inspired by Bose. They are using a technique known as active noise cancellation. They are using a processor in their earphones and headphones.

Until now we had dealt with 2 projects in detail so now in this project we will be seeing how we can operate different LEDs with a single transistor.

In the last post, we saw the working of LDR as a street light which was based on the concept of bjt as a switch. In this post, we will see LDR as a brightness controller

In the last post, we studied BJT as a switch. If you want to revise that concept then just watch the video given below.

In the last post, we studied different biasing techniques of the BJT transistor. So in this post and in the next post, we will be dealing with the application of BJT

In the last post, we studied what is biasing? and at the same time, we also understood why transistors should be biased? So in this post, we will see how the transistor is biased.

In the last blog, we studied about output characteristics of transistors and from there we understood that transistors can be operated in 3 different regions.

In the last post, we studied and implemented the input characteristics of the bjt transistor(bc547) . In this post, we will be focusing on the output characteristics of the BJT transistor(bc547). Why it is important to understand?. We will be seeing it in great depth. The output characteristic of the BJT transistor is plotted between the output current(Ic) and the output voltage(Vce) keeping the base current(Ib) constant. Consider 2 Cases for understanding output characteristics of BJT CASE:-1 :- When Ib=10uA and Vce & Ic are varying The input current Ib is fixed and Vce and Ic keep on varying. As Vce has increased Ic also increases but by a very small amount this is because the collector terminal(N-type) region is connected to the positive terminal. Since it is reverse biased therefore depletion region(D2) between collector and base increases. As depletion region D2 increases, electrons present in the emitter terminal suffers little resistance to migrate to the collect...

In an earlier blog, we understood some b asics of transistors and we saw that the power gain was more in CE configuration also it has high gain therefore

A transistor is a semiconductor device that provides the necessary amplification, it can be used as a switch, not only that in-fact various processors and controllers which we use in mobiles and various machines consist of millions or billions of transistors. But this blog will explain to you some basic information about the BJT transistor.

Cro cathode-ray oscilloscope is the device that is used to measure different parameters like voltage, current, frequency, phase angle, etc.

Last time we understood the working of capacitors in DC . In this post, we will try to understand how capacitors work in Ac.

A capacitor is a passive device that can store charge as the battery of mobile stores, used as tuning circuits on radio systems, etc. But the main problem is how a small device can perform such a task? Let's understand it in detail. A capacitor consists of two metallic plates separated by a dielectric material. The dielectric material is an insulator it can be glass, ceramic, plastic film, air, paper, mica, etc. Since a capacitor is separated by a dielectric material therefore when you charge the capacitor, charges get stored in plates. Let's say if you are charging a capacitor then the amount of charge accumulated on the plates of capacitors per unit voltage is known as capacitance. C=Q/V  Where C is the capacitance           Q is charge &           V is voltage Thus we can say that capacitance is inversely proportional to the voltage  i.e (C α 1/V) Capacitance also depends on the Area of plates(A), the...
