Decoupling caps

NO RATINGS

I grew up(?) in the 60,s and 70's and used recycled components from discard PCB's from Ravenscraig Steelworks.

It always troubled me that only one decoupling applied cap on VCC? Why not apply the same principle to VSS? Guess what, regarded as a freak or a loon but the designs worked, particularly the analog.

Old enough now to be tolerated as just an obstinate Curmudgeon, but principles stick like S to a blanket!

James Clerk Maxwell nailed and underpinned our theory, thanks JCM!

Good point. The reference is critical - one of the reasons signals are misread is that the ground and reference are not necessarily stable. More on that in a future blog.

New generation of FPGA with serail link at 10gbps and hifger, also needs very specific dc power integrity.

Also do you include DC Reference in dc poewr integrity?

IoT Network Shoot Out
July 16, 1pm EDT Thursday

Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion. Join in and ask his guests questions.
