Push pull amplifier

admin August 11, 2018 23 Comments
In this guide, let’s learn in detail about Push Pull Amplifiers. We’ve covered theory and applications behind a push pull amplifier. We’ve also demonstrated different types of push pull amplifiers, like Class A, Class B and Class AB push pull amplifier models. A push pull amplifier is an amplifier which has an output stage that can drive a current in either direction through through the load. The output stage of a typical push pull amplifier consists of of two...

A Note on Character LCD Displays

Mathew Kevin July 10, 2017 15 Comments
There are many display devices used by the hobbyists. LCD displays are one of the most sophisticated display devices used by them. Once you learn how to interface it, it will be the easiest and very reliable output device used by you! More, for micro controller based project, not every time any debugger can be used. So LCD displays can be used to test the outputs. Obviously, for last possibility, you need to know how to use this stuff...

IMAX – The Giant Step to Movies

john February 9, 2012 No Comments
Let a movie be in 3-D or an ordinary 70mm projection. We have always loved it for the story, sound effects, visual effects, and many other factors. But latest technologies have improved the way in which graphics and other effects have been introduced in each frame. Out of them IMAX is the most popular. The Fox introduced the first 70mm format, the Fox grandeur in 1929. Later the Cinema scope and vista vision widened the image from 35mm. Then...

MOS – Controlled Thyristor (MCT)

john January 24, 2012 6 Comments
Out of many semiconductor controlled devices, MCT is considered to be the latest. The device is basically a thyristor with two MOSFET’s built into the gate structure. A MOSFET is used for turning ON the MCT and another one is used for turning it OFF. The device is mostly used for switching applications and has other characteristics like high frequency, high power, and low conduction drop and so on. An MCT combines the feature of both conventional four layer...

A Complete Guide to Transformers

john August 3, 2018 56 Comments
Most of the electronic circuits used in Circuitstoday.com have different applications of the transformer. Therefore, it is important to know the working principle, construction and types of transformers used in different analog circuits. What is a transformer? A transformer can be defined as a static device which helps in the transformation of electric power in one circuit to electric power of the same frequency in another circuit. The voltage can be raised or lowered in a circuit, but with...

Modulation

john July 25, 2018 7 Comments
When audio signals are transmitted over thousands of kilometres through radio transmission, the audio frequencies that lie within the frequency range of 15 Hertz to 20 KiloHertz has very small signal power and thus cannot be transmitted via the antenna for communication purposes. The radiation of electrical energy is only possible at frequencies above 20 KiloHertz. The main advantage of high-frequency signals is that they can be transmitted over very long distances by dissipating very small power. Thus, the...

PCB Manufacturing Process

john November 22, 2011 3 Comments
A PCB is used to connect electronic components electrically. This is done by making conductive path ways for circuit connections by etching tracks from copper sheet laminated onto a non-conductive substrate. A PCB consists of a conducting layer that is made up of thin copper foil. The insulating layer di-electric is laminated together with epoxy resin prepreg. The most commonly used PCB type is the FR-4. Boards may be single sided or double sided. Double sided PCB can be...

Terahertz transistors are the new generation semiconductor transistors developed by Intel Corporation. The researchers in Intel had developed a new transistor structure that maintains Moore’s law and would lead them into the discovery of these high speed new generation transistors. The terahertz transistor basically has higher speed (in GHz), High power efficiency, and high heat reduction capacity. These transistors have a fast switching rate of more than trillion times per sec. They also have the capability to perform 50...

Thin Film Solar Cell

Vysakh June 6, 2011 8 Comments
Thin film solar cells are the new generation solar cells that contain multiple thin film layers of photo voltaic materials. The thin film solar cells (TFSC) are also known as Thin Film Photo Voltaic cell (TFPV). The thicknesses of thin film layers are very less as (few nano meters) compared to traditional P-N junction solar cells. According to the type of photo voltaic material used, the thin film solar cells are classified into four types. They are 1) Amorphous...
