Delta-Sigma Class D

[Jaka Racman]

Hi John,

it may be comforting to know that even the original guys are not doing any better than you : page 14 of B&O PEDEC implementation .

Alternative Korean solution does not seem to work better either.

Best regards,

Hey Guys!

Lots of hot shootin'! show-up
You're all very "smart" reading webpages left and right!
"Did you or did not ??"
That was my Q!
Anyway , you keep entertaining eachother , but I'm not interested in this childish debate.
Looks like I came to the wrong "forum".
It's my fault.

Regards.

Maybe i can help....i have done such an amp (delta sigma), based on the IR design pages. follow this thread.:

I think we are not talking about the same thing everyone. John Hope and me are talking about discrete-time delta-sigma modulation like it is used within A/D- and D/A- converters.

I am aware that some people call self-oscillating hysteresis-controlled class-d amps delta-sigma, like Pat does. Me personally I don't call them that way but I can't completely disagree with people doing so.

We don't know what "contitek" means with delta-sigma, and we may probably never find out since he wasn't that talkative.
