Electro-mechanical impedance (EMI) sensing technique based on smart piezoelectric materials has emerged as a potential tool for the implementation of an online monitoring system for structural health monitoring. Many nondestructive methods have limited capabilities in monitoring of the rubber aging in a continuous manner. In this study, the feasibility of the EMI sensing technique for the onlin...

In this paper, an advanced ultra-fast, broadband time domain EMI measurement system is described. Measurements were performed in the 30–1000 MHz range. The digital signal processing of EMI measurements allows to emulate in real-time the modes of conventional analogous equipment, e.g. Peak-, Average-, RMSand Quasi-PeakDetector. With the presented time domain measurement system the measurement ti...

This paper proposes the process to predict and analyze the conducted electromagnetic interference (EMI) emission using the impedance mismatch approach. Five steps of this process are introduced and analyzed. The impedance mismatch criterion is proposed based on current and voltage waveforms in time domain. The impedance mismatch fixtures and EMI measured results show how the relationship of imp...

This paper describes an electromagnetic interference (EMI)resisting Bandgap voltage reference. Its basic topology is a Kuijk Bandgap with a PMOS pass device and an active load, improved to generate a low voltage output (441.3mV) via substituting BJT by MOSFET while preserving a low temperature coefficient (TC). A double differential pair and a power-supply independent bias jointly enhance the E...

2799 According to a recent worldwide survey, current rates of de novo pacemaker and implantable cardioverter-defibrillator (ICD) implantation are higher than those of previous years at >700 000 and >200 000 per year, respectively. Parallel to the growth in cardiovascular implantable electronic device (CIED) use, technological advances have led to new sources of electromagnetic radiation. Modern...

In this paper, as the operating frequency of electronic systems increases, the electromagnetic interference (EMI) effect becomes a serious problem especially in consumer electronics, microprocessor based systems, and data transmission circuits. The Many approaches have been proposed to reduce EMI, such as shielding box, skewrate control, and spread spectrum clock generator (SSCG). However, the ...

This paper describes a new method for the selection of an appropriate signal line Electromagnetic Interference (EMI) filter. To date, EMI filter selection has been based on the measurement of the radiation of the entire device. The new selection method based on the signal’s Fast Fourier Transform (FFT) measurement has proved to be efficient. The EMI filter is optimized separately for each line....

The effects of highly out-of-band electromagnetic interference (EMI) on an RF front-end are experimentally evaluated. Irradiation at 60GHz with a moderate power is produced in the near-field owing to an open-ended WR15 waveguide fed by a Gunn diode. Surprisingly, we easily obtain the remote extinction of either the transmitter or the receiver of the front-end subject to EMI. The paper proposes ...

This work analyzes the advantages of broad-band time-domain the electrical measurement applied to electromagnetic interference (EMI) problems. The digital signal processing of EMI measurements allows to emulate in real-time the various modes of conventional analogous equipment. Since time-domain techniques allow processing the amplitude and phasing information of the whole signal spectrum in pa...

This work aims to compare the implementation of two metamaterials for reducing electromagnetic interference (EMI) in printed circuit boards (PCBs). Specifically, complementary split-ring resonators (CSRRs) and electromagnetic bandgaps (EBGs) were etched on the ground plane of a microstrip transmission line. Both techniques were compared as EMI filters, taking into account frequency response, si...
