Power Distribution Made Easy

Daniel Beeker  (Senior Principal Engineer, NXP Semiconductor)

Location: Room 204

Date: Thursday, August 29

Time: 11:00 am - 11:45 am

Track: ESC - Embedded Hardware Design & Verification

Format: Technical Session

Vault Recording: TBD

This session will present a simple EM physics and geometry based approach to designing power distribution networks on PCBs. From input power connection to the IC die, the simple rules discussed can be used to reduce power supply noise and improve EMC. New research will be presented on the impact of discrete components on radiated and conducted emissions, with an emphasis on cost analysis. We all are involved with developing products which generate, control and consume electromagnetic field energy.

This is not what we are taught.

Circuit theory pretends that electric energy is made up of electrons moving in the conductors. Switches add conductors, and the current instantly starts to move in the loop. The wires carry the energy, and the load instantly responds to the flow of energy.


Switches add new spaces, and the moving field carries the energy. It takes time for the field energy to move into that space. The moving field energy has no idea of what it is at the end of the new space.Field energy moving through a space induces current flow in the conductors. The magic here is the displacement current flowing through the dielectric at the wave front, completing the circuit.

Fields do all of the work!
