You're not going to learn layout from looking at a picture and never thinking about anything.

If parasitic resonances causing EMI aren't an obvious pitfall in a high speed power switching circuit, what is.
Please provide links to posts or documents not written by me explaining simple capacitor and transistor package RF resonance modelling, how to bring these systems close to critically damped in half bridges and how to do that when paralleling capacitors of very dissimilar sizes too.

BTW: Someone that is not capable of figuring out most of the part numbers and values on my PCB layouts won't be capable of designing any decent class D circuit anyway, so who cares?

I mean that there are already plenty of class D schematics published that people can study to learn to figure out parts and values before starting to look at PCB layouts.

You don't start thinking, when you look a PCB?


If you really find such links with key informations within five minutes, - these links would be a good contribution for the 'Class D Design Issues' thread.

Furtheron I have to correct myself. The thread were Eva kicked me to the goal 'What the hell are you waiting?' was at DIYhifi.org
