Pulse Width Modulation : PWM using Arduino

Aswin Babu G K — Fri, 10 May 2013 05:59:50 +0000

Pulse Width Modulation or PWM is a method of Digital to Analog Conversion. It helps in delivering analog average voltage using digital pulses of variable pulse width. By controlling the on time and off time, we can generate an analog average voltage using the digital pulses. PWM has a wide range of application. It is […]

Bridge Rectifier

vivekvs — Sat, 08 Dec 2012 17:33:34 +0000

Rectifier A rectifier is a device that converts AC into DC. The power available to us is in the form of AC. But almost all electrical equipments work on DC. So we need a converter that converts AC into DC. We employ a rectifier circuit for this purpose. Rectifiers are basically classified into Half Wave […]

Implementing XOR and XNOR Logic Functions using Diode Bridge and Transistor

Ligo George — Mon, 28 May 2012 05:03:26 +0000

Using DTL (Diode Transistor Logic) we can implement XOR and XNOR Logic Functions with a minimum number of Discrete Components. When we need to design Logic Circuits operating for higher than standard supply voltages, such as 30 and 24V, we can implement it by using regulators with standard logic family and interfacing it through Level Shifters. Alternatively we can implement […]

Optical Transistors Out of Silicon : Significant step towards Optical Computing

Ligo George — Fri, 04 May 2012 15:35:09 +0000

We all know that electrons are good at processing information, but they are incapable of carrying information over long distances. On the other hand, Photons can carry information all around the planet but their processing is hectic. So we use electrons for processing and photons for long distance data transmission. Thus we need significant amount of […]

Inside a Crystal Oscillator…….!!

Ligo George — Sun, 08 Apr 2012 07:06:34 +0000

A crystal oscillator is an electronic oscillator circuit which uses inverse piezoelectric effect, ie when electric field is applied across certain materials it produces mechanical deformation. Thus it uses mechanical resonance of a vibrating crystal of piezoelectric materiel to create an electric signal with very precise frequency. They have high stability, quality factor, small size and low cost and this […]

More Energy Efficient Transistors through Quantum Tunneling

Ligo George — Sat, 31 Mar 2012 13:59:16 +0000

Researchers at the University of Notre Dame and Pennsylvania State University had announced that they had developed Tunneling Field Effect Transistor (TFET), which takes the advantage of a peculiar behaviour of electrons at quantum level. We know that transistors are the basic building block of electronic devices that power this digital world. The growth of computing […]
