App note: Need for power and ground cleanliness:

Some tips and tricks on how to reduce noise on PCB power and ground traces. It warns digital engineers that the analog nasties are lurking in power supplies, and can cause unexpected surprises for inexperienced PCB designers.

Many times electronic system failures are blamed on the parts when the real cause was human error. Of these human errors, the most common is poor understanding of analog in a digital world. All too often brilliant digital designers have never been taught analog techniques because engineering schools are reducing the amount of analog taught. Maxim, however, is an analog mixed-signal Company. In this application note we share some analog concepts that will help overcome common “human” error and improve analog circuits around the system.
