The dielectric of the microstrip in printed circuit boards (PCBs) fabrication usually consists of two layers: the solder mask layer and the substrate layer.

In addition, the foil surface roughness cannot be ignored for the conductor loss modeling. In this work, an extraction method with high accuracy is proposed to characterize the dielectric material and foil surface roughness properties from the measured S-parameters with known cross-sectional geometry up to 20 GHz. With the extracted properties, the FEXT and insertion loss of the microstrip can be estimated more accurately, providing design guidelines for PCB design and the material selection of the microstrip.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"1 ","pages":"130-139"},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67842403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach can reduce the overall pin count and subsequently limit the package body size to remain within a ball grid array form factor. However, for printed circuit boards (PCBs) in which power vias are adjacent to signal vias, increased far-end crosstalk (FEXT) and resonance in insertion loss can be observed, due to the quasi-quarter-wavelength resonance of the power via stub. Using an analytical model and 3-D full-wave simulation models, a physical explanation for this unexpected resonance in differential signal pairs is proposed. Considering the difficulty in changing the pin map of the IC package, several PCB layouts are proposed to eliminate the power-via-induced quasi-quarter-wavelength resonance without the need to change the package pin map. Upon application of the proposed methods, the resonance is eliminated, and the FEXT is reduced.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"1 ","pages":"121-129"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67842402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The FEXT level is sensitive to the dielectric inhomogeneity of the stripline in fabricated printed circuit boards (PCBs). The dielectric of the stripline is manufactured with multiple inhomogeneous dielectric layers (IDLs) of various resin and glass fiber bundles. A marginal difference in the dielectric permittivity of the IDLs can lead to a significant change FEXT level. In this article, a practical FEXT modeling methodology for striplines is proposed by introducing the extraction method for \u0000<inline-formula><tex-math>${{boldsymbol{varepsilon }}}_{boldsymbol{r}}$</tex-math></inline-formula>\u0000 of IDLs. The new stripline model is constructed with three IDLs comprised of core, prepreg, and resin pocket, to improve the model accuracy. With the cross-sectional geometry and measured S-parameters of the coupled striplines, \u0000<inline-formula><tex-math>${{boldsymbol{varepsilon }}}_{boldsymbol{r}}$</tex-math></inline-formula>\u0000 of IDLs can be extracted. In addition, an analytical model to predict the FEXT polarity and magnitude of the stripline caused by the inhomogeneity is proposed targeted for prelayout application. The proposed models have been verified using measurement. The proposed models can provide useful analysis methodology and design guidelines to mitigate the FEXT level in high-speed systems, especially for high-volume PCB tests in the prelayout and postlayout stages.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"1 ","pages":"93-103"},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67842429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed method is based on the separation of a PDN into its local and nonlocal domains. The local domain is constituted by circuit components with the highest impact on the impedance of a specified power pin on a planar PDN. The rest of the PDN makes up the nonlocal domain, which could be of any planar shape. The nonlocal domain is characterized as a distributed circuit, preferably using a numerical electromagnetic (EM) simulator. The self-impedance of the pin depends on the placement configuration of capacitors in its surroundings. Using the pin impedance as a figure of merit, the optimal placement configuration is then sought in the local domain. The impact of the stationary domain is included in calculations as an indefinite impedance and the optimal placement configuration of capacitors is computed using an iterative approach. The proposed method avoids the use of a computationally intensive EM simulation at each iteration step, which significantly speeds up the analysis process.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"1 ","pages":"55-64"},"PeriodicalIF":0.0,"publicationDate":"2022-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67842425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the traditional method is employed in practically all the existing high-speed interface standards, the assumption of the constant, uniform termination impedance at TX and RX is not exactly correct and will lead to inaccuracy. The new method characterizes the mismatch conditions at the TX and the RX terminations on a per frequency point and per-port basis and, thus, produces more accurate results during the channel characterization and performance assessment. The mathematical computation procedure of the FDPP approach is introduced. Two representative TX/RX terminations and three typical channels representing mid/high/ultra-high losses are used to demonstrate the effects of the FDPP renormalization method. The obtained \u0000<italic>S</i>\u0000-parameters, eye-diagrams, as well as the channel operational margin (COM) figure of merits are compared to that generated using the traditional method.

Although, its computation has been widely studied in the static case and in the frequency domain for the dynamic case, its computation in the time domain (TD) has been only partially addressed. This article aims to fill this gap also pointing out their use in the framework of a TD solver. In particular, the modified numerical inversion of the Laplace transform (NILT) is adopted to compute the time samples of the partial inductance avoiding the cumbersome inverse Fourier transform (IFT). It will be shown that, in addition to the high accuracy, the delayed implementation of the NILT method strictly preserves the causality of the magnetic coupling. Furthermore, the use of Hermite interpolation allows us to significantly reduce the computational effort. The proposed method is tested by comparison with analytical formulas existing for coplanar zero-thickness regions and with IFT techniques for the both orthogonal and nonorthogonal geometries.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"1 ","pages":"32-42"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67842423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
