Inside a Crystal Oscillator…….!!

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 makes them superior over other resonators like LC circuit, ceramic resonator, turning forks etc. This image show a 8MHz crystal oscillator commonly used in microcontrollers and microprocessors. Although...

More Energy Efficient Transistors through Quantum Tunneling

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 power over the last 40 years had made possible by increasing the number of transistors that integrated in single silicon chip. Now we have more than...

First Sterilizable Flexible Organic Transistor

A team of researchers from Tokyo, Japan has succeeded in manufacturing a Sterilizable Flexible Organic Transistor on a polymeric film. It is enough robust under high temperature medical sterilization process. Now a days the applications of electronics are increasing day by day in health and medical area as more IT devices are being introduced. The series ageing society with declining birthrate is expecting more from electronics. On these backgrounds electronics has more expectations about organic transistors, which is a soft...

Light in place of Electricity !!!!!

A team of researchers from University of Pennsylvania led by Nader Engheta are working on the ways to use light in the place of electricity. Using nanotechnology they had developed the first physical illustration of lumped optical circuit elements. This development will be a landmark in the emerging field of science and engineering, called METATRONICS. The word 'meta' in metatronics means metamaterials. It is a developing research field where nanostructures and patterns are embedded in materials such that they can manipulate waves...

Single Atom Transistor

Australian and American physicists had developed a Single Atom Transistor, composed of an atom of phosphorous-31 isotope. They had demonstrated a working transistor composed of a single atom, which is about 100 times smaller than the 22 nanometer cutting edge transistor fabricated by Intel. This will be big strike towards the next generation computing. The researchers's uses a combination of Scanning Tunneling Microscopy (STM) and Hydrogen-resist Lithography to place single phosphorus dopant atom on the base of Silicon with a accuracy of of one...

Why we need Windows 8 ?

Start Screen : Microsoft is making one of the biggest upgrades through Windows 8. It replaces Start Menu with Start Screen which have tiles that contains shortcut to Applications, which is smiler to Metro interface on Windows Phone 7 OS. It will also introduce the Ribbon Interface which seen in Office 2007 to Windows Explorer. It will also launch a App store for Metro style apps that will support Windows 8. The Windows 8 has been designed to give support to ARM processors...
