We have been looking at creative power plane connections. For subsystems on
a board (of one or more chips) we are considering isolating the power plane
under each of them. This would be done with a narrow moat between the
rectangular island and the rest of the power plane. The moat would be
bridged with ferrites. The island would have a bulk storage (10 or 33uF)
for each ferrite and a number of bypass (multiple values) capacitors for
each chip. These would be connected to the solid ground plane. Their are
many pros and cons to doing this and we thought a wider audience might help.
Thanks & Regards, Keith
