INTROUCTION

In this fast moving world time delay is one of the most dreaded situations in the field of data communication. A delay in the communication is as bad as loosing the information, whether it is on the internet or on television or talking over a telephone. We need to find out different ways to improve the communication speed. The various methods adopted by the communication industry are the wireless technology, optical communications, ultra wide band communication networks etc. But all these methods need an initial capital amount wh ....etc

ppt for civil engineering on low cost building

Low Cost Housing is a new concept which deals with effective budgeting and following of techniques which help in reducing the cost construction through the use of locally available materials along with improved skills and technology without sacrificing the strength, performance and life of the structure.There is huge misconception that low cost housing is suitable for only sub standard works and they are constructed by utilizing cheap building materials of low quality.The fact is that Low cost hou ....etc

low inertia disc clutches ppt

Abstract

Operating Features Low Inertia Clutch
The Wichita Air-Tube Disc Clutch combines all the best features of the disc type clutch with all the advantages of the direct air engagement. The simplest and most trouble-free method of applying air pressure is through direct axial pressure application by compressed air in a special composition full-circle tube.

Wichita Clutches engage smoothly without noise, shock or impact and release completely in a fraction of a second. Extremely fast action is possible because ....etc

1. INTRODUCTION

With the proliferation of portable electronic devices, power efficient data transmission has become increasingly important. For serial data transfer, universal asynchronous receiver / transmitter (UART) circuits are often implemented because of their inherent design simplicity and application specific versatility. Components such as laptop keyboards, palm pilot organizers and modems are few examples of devices that employ UART circuits. In this work, design and analysis of a robust UART architecture has been carried out to m ....etc

DIELECTRICS AND MAGNETIC MATERIALS



Insulators

Some materials like glass, ceramic, polymers and papers are non-conducting materials.

They prevent flow of current through them.

They provide electrical insulation.

DIELECTRICS

the non-conducting materials when placed in electric field modifies the electric field and themselves undergo appreciable change are called dielectrics.

Energy Band Diagram

The forbidden gap Eg is very large for dielectr ....etc

A Low-Voltage Low-Power Comparator With
Current-Controlled Dynamically-Biased
Preamplifiers For DCM Buck Regulators

Hoi Lee
Department of Electrical Engineering,
The University of Texas at Dallas,
Richardson, TX 75080-3021, USA.



Abstract-

Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipate low power for low-voltage DCM ....etc
