Class D Delta-Sigma Amplifier

stepheno · 23rd November 2007, 10:36 AM

For those who are interested, here is my latest Class D Delta-Sigma Amplifier.
There is a German Audio magazine with design projects which is published monthly - can someone tell me what the name of the magazine is and/or direct me to their web site?
Thank you.

Where is the schematic.....??

Tekko · 23rd November 2007, 02:23 PM

Is it clocked or self oscillating ?

stepheno · 25th November 2007, 05:31 AM

Hello Tekko,
It is self-oscillating at approx. 400kHz.
Unfortunately I am not showing any circuits now.
Greetings.

Looks real nice

and I'm sure not only I am interested to hear more about your project.

Are you referring to:

Hello Nilsomat,
Thank you for your reply. No, it is not Elektor, something more like the American magazine AudioXpress. I believe it is one of the best magazines with practical audio projects. They also have a companion German magazine on practical loudspeaker projects.
Sincerely,
Stephen.
