“Don't gap your ground plane, there's never really a good reason to do that.” - Dr. Todd Hubing

Dr. Todd Hubing debunks the EMC myth. Dr. Hubing has authored or co-authored over 200 papers and presentations on electromagnetic modeling, electromagnetic compatibility (EMC), and the design of reliable electronic systems. In this episode he shares with us 30 years worth of knowledge, tested and proven facts about EMC.

EMC design guidelines: Top 4
- Solid ground planes should be gapped between analog and digital circuits.
- The decoupling capacitor should be located as close as physically possible to the IC’s power pin.
- On multi-layer boards, the best stack-up is...
- To suppress common-mode noise, the power input on a circuit board should have a common-mode choke.
