voltage doubler rectifier in particular the Greinacher voltage doubler rectifier‚ where the components used are mainly capacitors‚ diodes. Light emitting diode (LED) and 3-turn coil are also incorporated into Design 2 and Design 3 circuits. There are two main reasons of using a voltage doubler rectifier. Firstly‚ the LED require a forward voltage of 1.7V to 2.2V‚ and the 3-turns coil on the implant will not be able to pick up that much AC voltage‚ thus a voltage doubler rectifier is used to double

This is the story of the growth of the personal computer industry. The movie while based on historical fact‚ did alter things a bit for dramatic reasons. The Movie begins with IBM in the early 1980’s‚ the big brother in the computer world that everyone else feared.

The movie Pirates of Silicon Valley is a film based on the book Fire in the Valley: The Making of the Personal Computer by Paul Freiberger. The film was narrated by Steve Wozniak‚ co-developer of the Apple computer. The movie took off with Steve Jobs talking in a melodramatic way to the audience‚ it seems but as the angle of the scene shifts‚ it was shown that he was actually talking to a director and that they were currently in the middle of shooting a commercial which is for the Apple Computer
