Chapter 5

Circuits, layout and grounding

Publisher Summary

This chapter provides an overview on circuits, layout, and grounding. Designing for good electromagnetic compatibility (EMC) starts from the principle of controlling the flow of interference into and out of the equipment. One can conceive the EMC control measures as applying at three levels, primary, secondary, and tertiary. Control at the primary level involves circuit design measures such as decoupling, balanced configurations, bandwidth and speed limitation, and also board layout and grounding. The first design step is to partition the system. A poorly partitioned or nonpartitioned system may have its component subsystems separated into different areas of the board or enclosure, ...
