have relatively high impedance connections to the internal
planes. If high switching currents must be routed through vias
and/or internal planes, use multiple vias in parallel to reduce
their resistance and inductance. The power components

should be kept close together. The longer the paths that con-
nect them, the more they act as antennas, radiating unwanted
EMI.
