This paper discusses a novel design of Power Distribution Network (PDN). By physical structuring of the power plane into repetitive symmetrical and asymmetrical segments of varying size, suppression of the propagation of unwanted noise throughout the PDN over a wide frequency range is achieved. Prototype boards were built on standard FR4 and thin FR4 substrates and characterized using a Vector Network...
Radiated emission testing of electric components, modules and systems is mandatory. Such tests are performed in absorber-lined shielded enclosures during the development process. Due to strict time schedules, limited access to EMC measurement facilities and cost reasons, alternative methods are needed. This contribution presents an approach for a pre-compliance test method for radiated emissions of...
The EET (Extra Element Theorem) is a useful tool to investigate the impact of mismatch problems at the input and output ports of three port networks such as the Artificial Mains Network (AMN) used in conducted emission tests. The conformal mapping of the input/output transfer function allows to understand the implications of mismatches of the AMN at the EUT port and at the 50 ohm receiver port. The...
