BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two

In 1965‚ Dr. Gordon Moore working as the Director of R&D for Fairchild Semiconductor published a paper titled “Cramming more components onto integrated circuits”. In his paper‚ he discusses the future of electronics and how these “integrated circuits will lead to such wonders as home computers—or at least terminals connected to a central computer—automatic controls for automobiles‚ and personal portable communications equipment”. He also discusses how the rate in which the number of transistors

ELECTRONIC DICE . TO CONSTRUCT AN ELECTRONIC DICE USING LEDS . BACKGROUND: LED’s History The first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round. However‚ no practical use was made of the discovery for several decades. Independently‚ Oleg Vladimirovich Losev published "Luminous carborundum [[silicon carbide]] detector and

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

memory of a river. Someone may have a lot of memories of swimming in a river while someone else may have memories of journey by boat or launch on rivers. On the other hand‚ many of us also experience the cruel face of rivers during flood. But‚ memory of river is a common characteristic of the people of Bangladesh‚ a country crisscrossed by rivers. Actually‚ the rivers of Bangladesh mark both the psychology of the nation and the life of the people. But‚ unfortunately‚ our memories of rivers are declining

Case study: PETRIE’S ELECTRONICS Jim Watanabe looked around his new office. He couldn’t believe that he was the assistant director of information technology at Petrie’s Electronics‚ his favorite consumer electronics retail store. He always bought his new DVDs and video games for his Xbox 360 at Petrie’s. And now he worked there too. The company had made some smart moves and had done well‚ Jim knew‚ but he also knew that competition was fierce. Petrie’s competitors included big electronics retail
