Re: Why return path in PCB is as significant as signal path with an example
Hi,
do an internet search for:
"return path discontinuities"
"stripline return path"
"high speed layout guidelines"
and so on
...and you will find lots of documents, descriptions, tutorials ...

Re: Why return path in PCB is as significant as signal path with an example
Nothing happens until you close the current loop.
That is "the path". Not just the part you think is
"signal". The "signal" trace should be signal and nothing
but (in a perfect world). The return, that's a shared
resource unless you make it likewise clean and single
purpose.
Like, you may take a limo to the prom, but you are
going home on public transportation. So watch where
you sit, because that tux has a cleaning deposit.
