An efficient and unconventional modelling approach is established for the investigation of power delivery network (PDN) constituted by a multilayer printed circuit board (PCB) structure. The proposed model is applied to the power integrity (PI) analysis through a PDN structure with power/ground planes, vias and decoupling capacitors. The modelling methodology is based on the tensorial analysis of...
In the integral equation method for solving electromagnetic problems with thin conducting structures, there are several unfavorable factors. The individual electric field integral equation (EFIE) and magnetic field integral equation (MFIE) may deteriorate the conditioning of matrix equations due to their degeneration when the thickness reduces. Also, there are more near-interaction evaluations in...
In this letter, we propose and demonstrate a compact, low-cost, and easy to manufacture microstrip line with two open-circuit stubs to alleviate impedance mismatching of a packaged 40-Gb/s electroabsorption modulator integrated laser (EML) module. For comparison, two 1550-nm EML modules are fabricated, the only difference being that one of them is made with open-circuit stubs, while the other is not...
Different from the existing main-circuit topologies of the HVDC converters, this paper presents a class of improved converter structures constructed by Inductive Filtering (IF) method, which can be used to further construct different HVDC transmission modes. Firstly, the basic operating principle and the technical characteristics of the IF method based HVDC converter is theoretically analyzed. Then,...
