This presentation 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 is presented on the impact of discrete components on radiated and conducted emissions, with an emphasis on cost analysis. This course will, after an introduction to EM field behavior, describe several effective methods for designing the spaces used to deliver power on a PCB. These methods are driven by considerations for how fast the switches are changing states and the geometry of the spaces and placement of components to properly delivery energy to prevent EMC and signal integrity issues.
