I have a question regarding the return currents
flowing through the nearest reference plane in a
multilayer PCB stackup. I dont understand the concept
of return current flowing through the power(VCC) plane
if it happens to be the nearest plane to the current
carrying trace. When the driver makes a low to high
transition current flows from the vcc plane(rather the
bypass cap) into the Vcc pin of the driver and out of
the I/O pin and into the receiver(load) and then
finally into the ground and again re-enters the Vcc
pin of the driver making a current loop. In the above
scenario how does the return current flow through the
Vcc plane if i happens to be the nearest ref plane and
not the ground plane itself as i have put in the
current loop above. Thanks in advance.
