Based on two-probe inductive coupling and two-port cascade network theorem, in-circuit impedance extraction of primary of operational transformer has been discussed and validated. The importance of this approach is to overcome drawbacks in existing on-line Frequency Response Analysis (FRA) which is used to monitor impedance of the transformer winding to detect movement or deformation of transformer...
The performance of the electromagnetic interference (EMI) filter under the condition without the Une impedance stabilization network (LISN) are revealed and analyzed from the perspective of the common mode (CM) and differential mode (DM) impedances of the switched-mode power supply (SMPS), AC mains, and LISN. The in-circuit CM and DM impedances of the SMPS, AC mains, and LISN are extracted with an...
In high-speed electrical designs, the in-circuit characteristics of the components are usually obtained from in-circuit measurements as the references for designers. The two-probe approach (TPA) is one of in-circuit measurement approaches by adopting the inductive coupling effects of the current probes, and it gains good accuracy below 30MHz. In this paper, we propose an improved two-probe approach...
Multi-interconnect systems (MIS) have become highly popular in high-performance and high-density electrical systems design. However, the ever-increasing clock speed and the ever-complicated interconnections make signal integrity (SI) become a critical design issue and in most situations several iterations are required to achieve optimal SI performance. For the MIS with one driver and N receivers,...
A printed compact antenna array for small wirelessly powered device operating at 900 MHz is proposed. The prototype is developed by printing antenna pattern on a 0.1-mm-thick flexible substrate and folding the printed sheet into a rectangular volume measuring 35 56 12 mm . The edge-to-edge distance between array elements is only . An isolation structure is added...
