PCB layout - tips & tricks part III

[AndersHa]

Hi!

The subject for this part is the great area of grounding. However, I limit the scope to PCB grounding. It’s not intended to be a complete guide but I have tried to describe a few aspects that I think may be the most important ones. Nice reading!

New is also the possibility to subscribe to the posts. What is your thought about this feature?

What feature? I cant see anything to read or comment on.....
Found it...
Regarding analogue and digital ground, most experts say use a contiguous ground plane not two connected by a star point? Though my view on the topic is a few paragraphs wont cover this issue, I would suggest you add some links to papers from the likes of Henry Ott, Ralph Morrison, Howard Johnson, Ti and any other relevant sources.
Similarly with regards to ground bounce, links to papers on decoupling (many sources here far too many to mention) and also links to information on simultaneous switching noise etc.

Hi Marce,

Thanks a lot for the feedback.
I agree on a contiguous ground plane in most cases. A separation in analog and digital ground adds issues that needs to be dealt with. But, still, I think analog ground can make sense in some cases.
My idea is that each topic in the blog should be practical, relevant and not too long. To add a few links make perfectly sense.
