“…This measurement consists in injecting electromagnetic disturbances through magnetic loops or electrical dipoles placed very close to the IC area under investigation. This technique has been successfully used for injecting local electrostatic discharges [6], [7], or coupling the IC with a interfering continuous wave [8]. In both cases, the injection probes are specific to the measurement and do not emulate real-case aggressor circuits.…”

This paper presents a new methodology to measure electromagnetic interferences in 3G mobile platform. The main objectives of this approach are to evaluate the near field coupling between two integrated circuits, and validate, in a predictive way, that the two devices can be mounted in a same package.The methodology consists in emulating the near field electromagnetic behavior of a disruptive chip. The emulation of the aggressor device is performed by means of a specific probe.Then a risk of interference analysis is performed to validate the EMC compliance between the two chips. This analysis provides valuable information about sensitive areas, coupling orientation and critical coupling distances by means of extraction.Details of this methodology are illustrated through a 3G mobile platform. Using this approach, chip-to-chip interferences can be investigated without requiring any specific EMC test board and with a low cost near field emulator.

“…Scientists have researched the immunity of components from different aspects. Some works refer to the immunity measurement of components including direct power injection [1], bulk current injection and near-field scan immunity [2,3]. Several modelling studies have also been used to predict microcontroller immunity, such as the input/output buffer information specification and the neural network method [4].…”

This study introduces an electromagnetic interference detection technique to increase the immunity of a microcontroller-based system in a complex electromagnetic environment (EME). The detection method is explained. First, the interference in the power supply and at the input port of the microcontroller is detected. The simulation results are achieved in both time domain and frequency domain. The measurement results are obtained to verify the correctness of the detection method and the application of the detection method in the automotive field is presented. The final objective of the work is to ensure that the microcontroller-based system works fast in a normal EME and correctly in a complex EME without adding too much cost.

“…Many research works [1][2][3][4][5][6][7][8][9][10][11][12][13] have exploited different crystal oscillator circuit architectures, which usually play the important role in improving EMI susceptibility, start-up, drive-level, and negative resistance dynamics of the crystal oscillator circuits. But they are expensive and exhibit inferior phase noise.…”
