Friday Afternoon Session I (1:15 - 2:45 pm)

Alternative Paths of the Return Current

  • Alternative paths of the low and high-frequency return currents
  • Return path discontinuities and radiation
  • Split power/ground planes, slots in power/ground planes
  • Measurement - Return current and impact of discontinuities

Reference Plane Current Distribution

  • Microstrip configuration
  • Symmetric and asymmetric stripline configuration
  • PCB configurations
  • Simulation results - PCB current distributions 

Differential - and Common-Mode Currents and Radiation

  • Common mode creation
  • Common-mode choke
  • Measurement - Differential and common-mode currents emitted by a SMPS
