- Abstract
- Closed-form expressions of radiated emissions from power distribution networks (PDNs) in packages are derived based on the equivalent lumped-circuitmodel. The expressions are validated with results from full-wave numerical computations and far-field measurements. The effects of the small planar PDN structures on radiated emissions are quantitatively investigated based on the sensitivity analysis. Using the closed-form expressions, a systematic procedure for developing quantified PDN design guidelines to suppress the radiated emissions is formulated, which is then demonstrated with a test prototype PDN. The method allows the electromagnetic compatibility aware PDN design in the initial design stage.
