PCB-Level EMC, part II


Defining and designing Power-Distribution-Networks (PDN) in Printed Circuit Boards is the core topic of this class. Taking into account three major aspects, the functional requirements for a high performance PDN are defined: Controlling voltage ripple, decoupling the various components and mitigating radiation. A thorough explanation of the physical obstacles to be overcome in order to meet these requirements yields the design of plane-based PDNs. These so called powerplanes exhibt a variety of important properties, which are explored and refined. The end result is an optimal PDN, which is not only superior in terms of voltage ripple and EMC, but also forms the basis for a physicaly correct layer stackup and layout. Finally, a live-simulation of a PDN is conducted, where the ideas and questions of the attendees interactively become part of the presentation. This illustrates very vividly the influence of the various parameters as well as critical issues like resonances and appropriate countermeasures.


The attendee is familiar with the various tasks of a PDN. Being aware of the many drawbacks of conventional PDN-designs, he sets up plane-based PDNs, unleashing superior performance, as well in terms of functionality as in terms of EMC. Thereby he avoids a multitude of potential EMI-issues usually related to PCBs. Furthermore, these PDNs are the basis for excellent Signal-Integrity and stable system performance.
