This paper presents a study on the design guidelines for the common-mode filters with cavity-backed dumbbell-shaped defected ground structures (CB-DB-DGSs). An equivalent circuit model was first developed to explain the physical insight of the CB-DB-DGS common-mode filter. With the help of the equivalent circuit model, the design parameters of the DGS and the frequency behavior of the filter are correlated...
This paper presents a system-level modeling method by integrating analytical and numerical methods to analyze conducted and radiated electromagnetic immunity of electronic systems. Through extracting the intrinsic behavioural characteristics from cables, PCBA (board, traces, vias, connectors and components) and enclosure by using the semi-analytical method, one equivalent circuit model is built which...
The paper presents an integrated electromagnetic immunity modeling, design and diagnosis system for EMI/EMC scenarios assessment and analysis of electronic devices/equipments. With extracting the intrinsic electric characteristic of PCB, a new modeling method which integrates transmission line modeling and behavioural modeling is proposed to be employed. The system is thus capable of modeling and...
This paper presents a system-level behavioural modeling method for electromagnetic immunity design and diagnosis of electronic devices/equipments by integrating with transmission line model. Through extracting the intrinsic behavioural characteristics of printed circuit board, one analytical model can be built for PCB which is conventionally described by using complicated transistor-level RLC circuit...
This paper presents a system-level conducted electromagnetic immunity modelling method. The proposed method is capable of simplifying the system into simple equivalent circuit model and IBIS-like PCB behavioural model which enables the electromagnetic immunity test to be carried out through a series of computer simulations with minimal computer resources.
