Driven by the abrupt miniaturization of mobile devices and demand for 3D-IC, Through Silicon Via (TSV) has been highlighted as the key technology for compactly integrating multiple dies of various functions as a whole system. However, due to the instability in the TSV fabrication process, various types of disconnection defects can be resulted during(More)
Dietary potassium may neutralize acid load and reduce calcium loss from the bone, leading to beneficial effect on bone mineral density. In this nationwide Korean population study, dietary potassium intake was associated with improved bone mineral density in older men and postmenopausal women. Nutrition is a major modifiable factor that affects bone health.(More)
Simultaneous switching noise (SSN) is caused by the simultaneous switching of a group of I/O drivers, and is proportional to the total inductance and the rate of change of the switching current. This often leads to signal distortion and degradation of signal and power integrity of systems. Furthermore, with the continuously decreasing operating voltage,(More)
—High-power wireless power transfer system (WPT) with high voltage and/or high current can be very dangerous to both engineers and consumers because the probability of explosion is much higher than that of low-power WPT system. Therefore, safety and reliability issues of a coil module in WPT systems should be verified before the actual experimental test. In(More)
Wireless power transfer (WPT) technology has recently emerged as an innovative and promising technology, and its electromagnetic compatibility (EMC) has become a significant issue. In this study, we investigated the electromagnetic (EM) radiated emission and interference generated by WPT systems using resonant magnetic field coupling, especially in(More)
There are multiple electrical devices on automotive system, which are control devices, communication devices, and digital devices. Each electrical device can generate magnetic field, one of the critical radiated electro-magnetic interference (EMI) elements. The operating frequency of each device is different and it means that the bandwidth of magnetic field(More)
