Design Considerations
Ground Loops
Ground loops occur when different circuits are
given multiple paths to common or earth
ground, as shown in Figure 8. Multiple ground
points can slightly different potential and cause
current flow through the circuit from one point to
another. This can result in additional noise in all
the circuits. To eliminate the problem, circuits
should be designed with a single ground con-
nection as shown in Figure 9.
Parallel Power Distribution
Figure 10 shows a typical parallel power distri-
bution design. Such designs, sometimes called
daisy chains, can be used for very low output
currents, but are not normally recommended.
The voltage across loads far from the source
can vary greatly depending on the IR drops
along the leads and changes in the loads clos-
er to the source. Dynamic load conditions
increase the potential problems.
Radial Power Distribution
Radial power distribution is the preferred
method of providing power to the load. Figure
11 shows how individual loads are connected
directly to the power source. This arrangement
requires additional power leads, but it avoids
the voltage variation problems associated with
the parallel power distribution technique.
Mixed Distribution
In the real world a combination of parallel and
radial power distribution is often used. Dynamic
and high current loads are connected using a
radial design, while static and low current loads
can be connected in parallel. This combined
approach minimizes the drawbacks of a parallel
design when a purely radial design is not feasi-
ble.
