Hello Si-list,
I have a question: I have a CMOS driver that drives a strip-line trace 
referenced at top to Vdd supply power plane and at bottom to vss ground plane.  
The trace is terminated to vdd only.  Since there is no termination to ground, 
will it be any return current flowing through the ground plane or only through 
the Vdd power plane?
Thanks,
Paul
