Decoupling caps

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.

High speed serial link - special requirement

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?
