This page is dedicated to Electronic Circuits and it also contains links to some of the major semiconductor companies. Here you will find easy to design circuits which can be used as projects for students. For AUDIO enthusiast, I have included a few Power Amplifier designs to provide some punch to their Discmans.
The page currently contains a Single Chip Power Amplifier using NATIONAL SEMICONDUCTOR's IC and a POWER INVERTOR which is as basic and as straight forward as it can be. The Invertor circuit contains a transistorised version and a more advanced POWER MOSFET version. The latter being more efficient but also more expensive.
