It has been shown that for loosely coupled single-ended transmission lines, far-end crosstalk (FEXT) on a victim line is proportional to a scaled negative derivative of the far-end signal on the aggressor line; thus, a variety of crosstalk derivative cancelation techniques have been developed. However, when channels are tightly coupled, the derivative cancelation method fails, thus preventing its use at higher data rates. In this article, we examine the derivative-based crosstalk-cancelation technique, and then provide reasons as to why it fails at higher data rates and develop a rule establishing when it can be used. We also propose the use of a time delay neural network crosstalk canceler (NNXC) to cancel FEXT. The proposed crosstalk canceler can operate at significantly higher data rates than cancelers using the derivative-based method. The NNXC can also be used in systems with multiple tightly spaced channels, which is not possible using the derivative method. Furthermore, when a clock signal is available, such as in DDR systems, it can be used as part of the network's training sequence–––significantly improving the performance of the NNXC in reducing far-end crosstalk. Several simulations are shown depicting the superior performance of the NNXC canceler, including in a realistic DDR5 channel with tightly coupled lines.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"3 ","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138633934","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}

However, including VRMs in power integrity simulations has been challenging, because power electronic simulation tools are not compatible with typical power integrity simulation tools, and encrypted VRM models for SPICE tools are typically not sufficiently accurate to capture the non-linear behaviors under various load conditions. Herein, a SPICE-compatible behavior modeling method is proposed, which is applied and validated for a practical multiphase VRM in a mobile platform. The simulation model adequately captures the control loops of the VRM, such as single-voltage and multiple current feedback loops. By combining the parameter-based equations from the voltage and current feedback networks, the model reproduces pulse-width and pulse-frequency modulation-based VRM operations. For validation of the behavior model, the design parameters are determined through a two-step process. Finally, the proposed behavior modeling method is experimentally validated with an evaluation board with various load conditions.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"2 ","pages":"122-133"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109157524","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}

Specifically, the article focuses on optimizing design elements in the interface, including the interconnecting transmission line, the T-coil, the transimpedance amplifier (TIA), and digital equalization tap weights. To optimize the optical link, we use a combination of analytical models, electromagnetic simulations, and machine learning techniques to describe different interface elements as most appropriate for each. Finally, we use the genetic algorithm to obtain optimal design parameters. The proposed optimization approach leads to a quick design time and reveals insights into some of the best design practices. As an example, we use the proposed method to investigate the relationship between optimal transmission line width and the amount of equalization available on the receiver. These conclusions are further supported by measurements taken on an assembled prototype with various PD-to-TIA interconnect lengths.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"2 ","pages":"111-121"},"PeriodicalIF":0.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/9745882/10040918/10227602.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67896248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventionally, differential-equation (DE) circuit and cavity type models have been applied to compute the inductive behavior of the plane-to-plane inductance. However, these methods are not suitable for the case where the structures are perforated or involve other uneven structures. In this article, a new partial-element-equivalent-circuit (PEEC)-based method is presented to compute the inductance of parallel plate-like planes and other structures. Examples are given to show that the new method can efficiently compute inductances for multiple integrated circuit power vias, power/ground planes, and multiple decoupling capacitors. The proposed model is validated with both full-wave CEM simulations as well as with measurements. Further, the speed and the accuracy for real PCB and package designs are presented to validate the efficiency as well as the accuracy of the proposed approach. An important aspect of any approach is the limitations for solving real life problems. In this article, we consider important issues related of plane-pair PEEC to power distribution evaluations. Specifically, we show that large holes in planes can accurately be modeled. This is a difficult issue for DE methods. Another surprising practical issue is the accuracy obtained even if the planes are not of the same size. We also consider the speedup, which can be obtained in comparison to solutions for other approaches. This is due to the sparsity of the coupling for the rapid coupling decrease with distance. This short-distance coupling also increases the maximum frequency for which the method can be applied.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"2 ","pages":"103-110"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67896249","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}

In this article, a mode-decomposition-based equivalent model of a high-speed via that can be applied at frequencies up to 100 GHz is proposed for the first time. The equivalent model for modeling the via transition consists of upper and lower via-to-plate capacitances and equivalent parallel-plate impedances, owing to the fundamental mode and higher order modes for parallel-plate, all of which can be calculated from physical geometrical parameters. The via-to-plate capacitances are calculated by using the domain decomposition method in the antipad domain and via domain. The parallel-plate impedances representing via and parallel-plate coupling are calculated with the mode decomposition method for different parallel-plate modes (fundamental and higher order modes) in the parallel-plate domain. The proposed equivalent via model provides more accurate results in the high-frequency range than previously proposed methods. Because the impact of higher order modes on parallel-plate impedance is considered in the proposed mode-decomposition-based via model, and the effects of higher order modes are prominent at high frequencies for printed circuit board (PCB) vias with typical dimensions. The proposed model is validated with numerical examples, which show good correlation at frequencies as high as 100 GHz. The proposed model can be applied to high-speed via transitions in PCBs and packages.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"2 ","pages":"74-83"},"PeriodicalIF":0.0,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67898144","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}

Various issues related to signal and power integrity come into picture at high-frequency operations, e.g., jitter, cross-talk, electromagnetic interference, etc. In this article, an analysis of the CMOS inverter in presence of deterministic noise is presented. An analytical approach is presented which estimates jitter in CMOS inverters in the presence of power supply noise (PSN), data noise (DN), and ground-bounce noise (GBN) by deriving analytical relationships. The proposed analytical method takes into account the device parameters to model timing uncertainty. The expression for jitter is obtained by estimating the deviation of each transition edge from its ideal position. Several examples (simulations as well as measurement) are presented to validate the proposed modeling. These examples include comparing the analytical results with the simulation results obtained using an SPICE-based simulator as well as doing the same with the experimental results using two different CMOS inverter integrated circuits (ICs). In order to test the independence of the proposed modeling approach on a specific technology node, the results are verified by considering different technology nodes such as: 40 nm, 65 nm, and 180 nm from United Microelectronics Corporation. Also, two different ICs (M74HC04, and MC74AC04 N) from different vendors are used for measurement. The results obtained using the proposed methodology are in close consonance with those obtained from simulations using the SPICE-based simulator and the experiments.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"2 ","pages":"64-73"},"PeriodicalIF":0.0,"publicationDate":"2023-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67898145","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}

Two scenarios, 0 dB and high loss, with varying levels of dual-side far-end crosstalk (FEXT) and near-end crosstalk applied, are studied. A detailed description of the ENRZ algorithm is provided. The reasons that lead to the performance edge of ENRZ in contrast to the rest three modulations are analyzed. The methodologies of injecting the crosstalk interferences into the differential/multiwire channels are discussed. A widely existing issue in computing FEXT is pointed out, with the recommended technique presented. A holistic channel simulation method called frequency domain matrix multiplication is employed in this study for its better handling of multiwire-based channels. The simulated eye diagrams obtained with the four modulation techniques are compared and analyzed. The study shows that ENRZ's inherence of insensitivity to channel loss makes it remain robust under the interferences of crosstalk in comparison with the other three types of modulations. Meanwhile, overall ENRZ and NRZ are more robust than PAM3 and PAM4 when the crosstalk level increases.","PeriodicalId":100646,"journal":{"name":"IEEE Transactions on Signal and Power Integrity","volume":"2 ","pages":"53-63"},"PeriodicalIF":0.0,"publicationDate":"2023-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67896250","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}
