ANALOG POWER SUPPLY
Two similar approaches to improving or eliminating the problems
associated with grounding excess transient currents involve star-point
ground systems. One approach is to star-point the different grounds at
the power supply origin, thus keeping the ground isolated. Refer to
Figure
Another approach is to star-point the different grounds near the analog
ground pin on the microcontroller by using small traces for connecting
the non-analog grounds to the analog ground. The small traces are
meant only to accommodate dc differences, not ac transients.
This star-point scheme still requires adequate grounding for digital and
analog subsystems in addition to the star-point ground.
