I'm new to the list so this may have been mentioned before. An excellent series on grounding devoted to mainly PCB issues but the thinking is universal: http://www.edn.com/design/analog/4394761/Successful-PCB-grounding-with-mixed-signal-chips---Part-1--Principles-of-current-flow   There are 3 parts to the article - links are available at the end of every section to the next section. Simon Engineering is the art of making what you want from what you can get at a profit.

Simon, Welcome to the list! Since I'm working on grounding problems for some 20 years I can confirm this an important issue. Many of my engineer colleagues do not have a clue about it. The article you recommended describes the thing very clearly. I will recommend it my colleagues and use it to teach my students. Thank you Volker Am 21.12.2012 13:28, schrieb M.

FWIW I've combined all 3 parts into one PDF and put them on KO4BB's great website. Look in Manuals 10) Recent Uploads for "Reference na na Other-EDN article SuccessfulPCBgrounding". Since my PDF did not have working links I used a zip file with a Word doc for the links. Another article that may be useful is from Electronic Design, see http://electronicdesign.com/print/components/harmonic-distortion-and-board-layout17808 Bob LaJeunesse ----- Original Message ---- > From: Volker Esper <ailer2@t-online.de> > To: M.

Would it be possible to send me this zip file? Didier had to take it off his website because of EDN sending him a DMCA notice.
