The door to a microwave oven forms part of the heating cavity, allowing access to the oven interior. The seal around the door is never perfect, so electromagnetic fi elds will leak out of the oven, potentially interfering with other electrical equipment or exceeding safety limits for power levels in human operators. Oven designs have to meet legal requirements for the amount of power which can ...
Applications of the method in optimizing arrangement of antennas in small satellite platforms are investigated. Satellite antenna layout EMC simulation modeling, analysis and design optimization has been described in the article. Taking a LEO satellite prototype, we have established a satellite simulation model simulation model and the respective antennas, and calculate the degree of coupling b...
A modern operating theatre or intensive care unit contains many pieces of electronic equipment, which all have to function safely and reliably in close proximity to each other. To ensure that this can happen, it is vital for those who design, manage or use electro-medical devices to consider electromagnetic compatibility (EMC). In a hospital, the electromagnetic environment can be quite harsh, ...
The electromagnetic compatibility (EMC) of integrated circuits (IC) has permanently gained more and more significance during the last years. At present, ICs are moving towards operation frequencies in the GHz range with rise and fall times in the order of a few pico seconds. The high transition rates, as well as the increased complexity of ICs, lead to high electromagnetic emissions and weak su...
In recent years, several new methods for IC-level electromagnetic compatibility (EMC) testing have been introduced. Therefore, a handy vehicle for IC-EMC testing is required to validate the effectiveness of the new IC-EMC testing methods. This paper proposes an 8051 MCU for IC-EMC testing platform with in-system programming (ISP) and decoupling capacitor (decap) functions. In order to reduce th...
This paper presents the results obtained with a specific test mask designed at Motorola for the study of the electromagnetic parasitic emissions in integrated circuits (IC). First, origins of parasitic emissions are presented for CMOS circuits, and electromagnetic compatibility (EMC) measurements of IC emissions are detailed: a radiated measurement method with respect to the IEC61967-2 standard...
The EMC Society's Hall of Fame Award was initiated in 2007 to honor six Founders the Society who attended IEEE International Symposium on Electromagnetic Compatibility. original awardees were Sam Burruano, Milton Kant, Vince Mancino, James McNaul, Ralph Showers, and Tony Zimbalatti.
This paper deals with the modeling of integrated circuits for electromagnetic compatibility (EMC) analysis. With reference to complex integrated circuits that usually include huge core logic blocks, analog and mixed signal circuits as well as power sections (smart-power system-on-chip), the paper shows a new behavioral model whose parameters can be derived on the basis of scattering parameters ...
This work presents the analysis of radiated EMI problems associated with DC-DC buck converters and the solutions for minimize the reverse recovery of the Drain-Bulk diode of the synchronous switching MOSFET. The DC-DC buck converter topology is used in computers and telecom applications because of its high power efficiency and multiple DC levels. For reducing the reverse recovery and its relate...
