As data-rate increases, bit time (UI) is shrinking, and accurate measurement of the data valid window and jitter become very important. Power distribution network (PDN) noise affects the overall system timing. The conventional way of PDN modeling approach in NAND Flash memory System level analysis, cannot accurately predict the system level jitter and deviates from the actual product level performance. In this paper, an accurate method for PDN-induced jitter analysis in NAND Flash system-level operation is described. Simulated PDN-induced jitter results are validated through characterization system and product level measurement jitter.","PeriodicalId":284818,"journal":{"name":"2022 IEEE 31st Conference on Electrical Performance of Electronic Packaging and Systems (EPEPS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126607339","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 radiation efficiency, peak gain, and impedance bandwidth improve upon encapsulation of the antenna with IC packaging epoxy mold compounds (EMCs). In addition, high-frequency conduction and dielectric losses are analyzed, and their effects on antenna radiation efficiency are quantified in this paper. The overall radiation efficiency is shown to improve by 25%, peak gain by $sim 3 boldsymbol{text{dB}}$, and the-10-dB return loss bandwidth improves from 3 GHz to 18 GHz by encapsulating a 300-GHz on-chip patch antenna within commercially available EMCs.","PeriodicalId":284818,"journal":{"name":"2022 IEEE 31st Conference on Electrical Performance of Electronic Packaging and Systems (EPEPS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114288162","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 work we present and verify a novel wiring strategy for links with a symmetrical pinfield-to-pinfield topology that reduces crosstalk significantly and requires no extra shielding vias. By twisting the orientation of the $p$ and $n$ wires of the differential stripline pair, a cancellation of the crosstalk between the differential via pairs is achieved. It can be implemented without any additional space requirements. The proposed design is fabricated and the crosstalk is measured with a vector network analyzer. It is shown that small changes in the orientation of the wiring in the pinfield region can reduce far-end crosstalk significantly.","PeriodicalId":284818,"journal":{"name":"2022 IEEE 31st Conference on Electrical Performance of Electronic Packaging and Systems (EPEPS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125254701","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}
