Abstract
The noise voltage in the reference or ground of a printed
circuit board is often the cause of unwanted radiated
emission. Power supply planes attribute to the noise
voltage. By replacing the power supply planes by tracks,
the noise voltage in the reference or ground can be
reduced, which leads to a considerable reduction of the
radiated electromagnetic fields. A potential disadvantage
of using power tracks is a decreased power
quality, due to a higher ripple voltage. Actual circuits,
fed via power planes or power tracks have been designed
and measured showing the impact on radiated
electromagnetic fields with constant power quality.
