Design for Electromagnetic Compatibility & Signal Integrity

Course Length:



Design for EMC/SI (Electromagnetic Compatibility & Signal Integrity) is our flagship EMC design class. It addresses the control of EMI (Electromagnetic Interference) at the box level through proven design techniques. This three-day course provides a comprehensive treatment of EMC/SI “inside the box.” This includes digital and analog circuits, printed circuit board design, power electronics, I/O treatments, mechanical shielding, and more. Please note – this class does NOT address “outside the box” issues such as cable design, power wiring, and other systems level concerns. Day 3 discusses EMI Troubleshooting Guidelines with case studies. Each student will receive a copy of the EDN Magazine Designer’s Guide to EMC by Daryl Gerke and William Kimmel, along with a complete set of lecture notes.

What you will learn:

  • How to identify, prevent, and fix over 30 common EMI/EMC problems in at the box/design level
  • Simple models and “rules of thumb” and to help you arrive at quick design decisions (NO heavy math).
  • Design impact of various EMC specifications
  • Practical tools, tips, and techniques
  • Good EMI/EMC design practices
