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

Technological issues In light of the intense competition facing the consumer electronics industry‚ manufacturers are constantly engaged in the creation of new products that would hopefully win consumers’ acceptance. However‚ against a backdrop of changing technology and sophisticated consumer wants‚ inventing a successful innovation is an uphill task. In this study‚ we chose two products‚ the portable MiniDisc player and the MP3 player‚ to represent the various innovations in the consumer electronics

Company Background: Samsung Electronics Samsung Electronics was established in 1969 in order to provide an engine of future growth for the Samsung Group. Though the electronics industry seemed promising in the 1960s‚ none of the Korean firms had advanced technology. Samsung began by producing low-end black–and-white televisions in a joint venture with Sanyo‚ a Japanese electronics company. With NEC‚ another Japanese firm‚ it produced Braun tubes and kinescope tubes. After three years‚ it began
