A Zener diode is a diode which allows current to flow in the forward direction in the same manner as an ideal diode‚ but will also permit it to flow in the reverse direction when the voltage is above a certain value known as the breakdown voltage‚ "zener knee voltage"‚ "zener voltage" or "avalanche point". The device was named after Clarence Zener‚ who discovered this electrical property. Many diodes described as "zener" diodes rely instead on avalanche breakdown as the mechanism. Both types are

1.0 Introduction 1.1 What is Semiconductor A semiconductor is a solid whose electrical conductivity can be controlled over a wide range‚ either permanently or dynamically. Semiconductors are tremendously important technologically and economically. Silicon is the most commercially important semiconductor‚ though dozens of others are important as well. 1.2 What is Semiconductor Industry The semiconductor industry is the collection of business firms engaged in the design and fabrication of

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

archive attachment. There are two separate detector units. Every detector unit consists of a dipole antenna‚ a choke and a diode. The antenna receives the GSM signals in media. Then a small amount of charge is induced in the choke. The diode demodulates the signal and finishes detecting. The diodes must be schottky diodes or germanium diodes. Since the forward voltage of a silisium diode is high‚ it won’t give a sufficient result in this circuit. LM358 amplifies the received signal. It contains two separate

full wave) is determined by the circuitry. THE DIODE In half-wave rectification only one diode is used. As you will recall from previous chapters‚ a diode is a check valve for electrical current. Current may flow only in one direction through a diode. It obtains its name from di-‚ meaning two‚ and -ode for electrodes. The electrodes are named the anode (positive electrode) and cathode (negative electrode). There are many different kinds of diodes. We will restrict ourselves here to just two types
