Indeed, the progress of power device downsizing allows higher switching frequencies and shorter switching times, which create significant high-frequency switching noise in power rails. More specifically for converters that operate under a range of loading, gate driving and biasing conditions, a behavioral model is necessary in the context where simulation only is not sufficient for proper prediction of the power integrity characteristics of a system under that range of conditions. This article proposes a power integrity model and a characterization methodology to predict voltage fluctuations on the power rails in simultaneous switching conditions on an array of switch-mode converters integrated in SiP.

To address the challenges of weak long-term dependencies and information ambiguity arising from excessively long network sequences in RE prediction for complex PCBs, our method begins by tokenizing and modeling each network combination. These combinations are then fed into the seq2seq model for training, supplemented with a multihead attention mechanism to enhance information connectivity. To validate the model's accuracy and efficiency, we compared our prediction results with those obtained from traditional full-wave electromagnetic simulations. Our approach significantly reduces the RE prediction time for the entire board from several hours to nearly one second. Moreover, the model exhibits high performance in RE prediction, with a mean absolute error of approximately 0.001 V/m. To verify the model's reliability, we applied the trained model to predict RE for brand-new entire boards and key networks, demonstrating its ability to accurately predict RE in previously unseen PCBs. Therefore, this method can be implemented for intelligent, full-automatic RE prediction in practical applications.","PeriodicalId":55012,"journal":{"name":"IEEE Transactions on Electromagnetic Compatibility","volume":"66 6","pages":"2027-2038"},"PeriodicalIF":2.0,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the bottom, a dielectric layer functions as a reflector.

Through simulation optimization, the slot structure is carefully designed to strike a balance between a high sensitivity and low effective center. To further elucidate the working principle of the slot probe, this article examines the effect of the probe's geometry on the effective center. The probe's design on a four-layer printed circuit board enables cost-effective fabrication without compromising stable performance. Operating within a frequency range of up to 30 GHz, the probe also effectively suppresses unwanted fields across a wide spectrum.
