The objective of power integrity is to produce a clean signal for the high-speed driver by supplying a good source. A good source needs to fulfill two criteria: 1) meet the DC power requirement and 2) reduce the power fluctuation caused by the AC current switch. This paper will discuss power integrity simulation using the 3D fullwave simulation tool CST STUDIO SUITE®. The accuracy of the simulation results are also compared with the measurement results.","PeriodicalId":231437,"journal":{"name":"2015 IEEE 19th Workshop on Signal and Power Integrity (SPI)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116006009","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 paper focuses on interconnections from one chip to a neighboring chip via an interposer. We use a typical silicon interposer with polymer applied to the redistribution layer on both sides and a minimal trace width and spacing of 10 μm. We point out important advantages as well as differences of the chip-to-chip interconnection in comparison to an usual integration using a separate package for each chip and a printed circuit board. The electrical behavior of the interconnections is simulated. We show by simulation that the electrical behavior of a 9 mm interconnection on the interposer is sufficient to drive a bus at 2 Gbit per second. The average power consumption of a state transition of the chip-to-chip interconnection is simulated and compared to the power consumption of a typical printed circuit board transmission line. The results show that the interposer interconnection consumes significantly more power per length than a typical printed circuit board trace because of its increased resistance. Therefore we do not recommend to further decrease the minimal trace width for chip-to-chip interconnections.","PeriodicalId":231437,"journal":{"name":"2015 IEEE 19th Workshop on Signal and Power Integrity (SPI)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122118101","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}

Both should be bounded to a certain limit, RL to ensure reliable clock recovery and RD to limit baseline wander. In a previous paper, we presented a very low overhead line coding with guaranteed maximum run length. In this paper, we propose a low overhead technique to bound the running disparity that can do up to 10x better than existing encodings in terms of overhead and for the same RD bounds. We furthermore show how we can combine this technique with our former one to build a low overhead, run length limited, and DC-Balanced Line Coding.","PeriodicalId":231437,"journal":{"name":"2015 IEEE 19th Workshop on Signal and Power Integrity (SPI)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129674122","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}

It is essential to understand and analyze the electromagnetic susceptibility of DLLs to ensure the proper operation of the system. In order to ascertain how the performance of DLL is affected by the external noise, we design a DLL using self-biased techniques and establish the noise immunity experiment with bulk current injection (BCI) method. We also construct the equivalent circuit model for circuit simulation and demonstrate its validity by comparing with the measurement results. Consequently, the RF noise immunity characteristics of the DLL varies with its frequency and magnitude. Particularly, we detect that the DLL circuit that we designed is very sensitive to the external noise with frequency around 75 MHz.","PeriodicalId":231437,"journal":{"name":"2015 IEEE 19th Workshop on Signal and Power Integrity (SPI)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115680228","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}

LC cross-coupled oscillator operates at 50 GHz and ILFD is supposed to provide the operation of divide-by-2 (/2). ILFD has a similar structure with the oscillator to adjust the frequency alignment between the oscillator and ILFD. As the 2nd-stage divider, CML frequency divider is applied with an inductive peaking structure.

Mobile devices powered by octa-core CPUs offer faster performance, but suffer the larger dynamic voltage droops, especially for the PCB with the single-sided component placement (SSCP). Some chip-package-board co-simulations using the chip power model and full channel S-parameters were taken to evaluate the different decoupling capacitor configurations, feedback line designs, and the voltage compensation technique between the power management integrated circuit (PMIC) and the application processor (AP). Evaluation results indicated that the proposed single-ended feedback line sensed the most accurate voltage droop on the AP side than the traditional differential feedback lines did. A careful power distribution network design with the early voltage compensation technique reduced 37% of decoupling capacitor cost in the SSCP PCB and achieved the dynamic voltage droop on the AP side less than 10% of supply voltage from the PMIC.","PeriodicalId":231437,"journal":{"name":"2015 IEEE 19th Workshop on Signal and Power Integrity (SPI)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128139601","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}
