By solving one-dimensional heat conduction equation in the channel self-consistently, self-heating effects on the I-V characteristics, signal delay and cutoff frequency of the CNTFET are studied. Simulated results indicate that the performance degradation of the CNTFET, due to self-heating effect, is quite low than that of silicon-based FET counterparts. Therefore, CNTFETs are good candidates for advanced active devices with low power dissipation and good reliability for high operating temperature.","PeriodicalId":185326,"journal":{"name":"2010 IEEE Electrical Design of Advanced Package & Systems Symposium","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133961223","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 performance of the ADC, however, is deteriorated by coupled power supply noises through hierarchical chip-PCB power distributed networks (PDNs). In order to design a high-performance system, modeling and analysis of power supply noise effects on the ADC are necessary, as the power supply noise is coupled to the circuit through the hierarchical PDN structure in multilayer PCB substrates. In this paper, a hybrid model is proposed for analysis of power supply noise effects on the ADC. The model combines two modeling mechanisms. First, the coupling ratio of the power supply noise is derived by the combined model of hierarchical PDNs at the PCB and the chip. Second, an analytical model is proposed using equivalent circuits for analysis of the power supply noise effects on the ADC. The ADC is designed using a 0.13um CMOS process. The proposed model and analysis are verified based on a simulation from 100kHz to 4GHz. The performance of the ADC is dominantly affected by characteristics of the on-chip circuit under 100MHz. It is also confirmed that the Effective Number of Bits (ENOB) of the ADC is strongly dependent on the hierarchical PDN impedance over 100MHz. Furthermore, there are peak points caused by inter-modulation (IMD) and cavity resonances of PDN structures.","PeriodicalId":185326,"journal":{"name":"2010 IEEE Electrical Design of Advanced Package & Systems Symposium","volume":"31 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125701873","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 shown that the influence of non-uniform currents can be relevant at frequencies above 10 GHz for typical printed circuit board dimensions. The contour integral method is applied to extract the current non-uniformity due to vias in close proximity. An identification of modes is carried out via a discrete Fourier transform. The energy content of the higher modes increases with frequency and via size. It is demonstrated by means of full-wave simulations that non-uniform via currents can lead to anisotropic electromagnetic fields in the antipad region and to the excitation of anisotropic cavity modes.","PeriodicalId":185326,"journal":{"name":"2010 IEEE Electrical Design of Advanced Package & Systems Symposium","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133266054","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}

A robust CDR jitter tolerance test should accommodate test criteria with extremely low bit error rate (BER) values, usually 10−12 or lower for typical industrial protocols. Using conventional methods, the time required to measure a complete set of CDR jitter tolerance values can stretch into weeks depending on the data rate. In general, measurement time increases tenfold for a similar tenfold reduction in BER. This translates to prohibitively long measurement times for BER values of 10−15 and lower. Statistical extrapolation for low BER measurement such as Q scale has been widely used in the industry, but this is only applied for transmitter measurements, specifically jitter measurements. This paper introduces a novel, fast measurement method for receiver testing based on the Q-statistical method to predict the BER for high-volume data transmission based on small sample data sets. Experimental data using this method show that extrapolated jitter tolerance values for BER values down to 10−15 can achieve an accuracy of 1.25 mUI. This innovative method improves the efficiency of jitter tolerance tests by significantly reducing measurement time. Furthermore, the method allows for the extension of measurement scope to cover previously unattainable jitter tolerance values for lower BER values. With these advantages, full jitter tolerance characterization on Altera Stratix® IV GX devices successfully meets very aggressive product rollout and time-to-market schedule, even with measurements for 24 protocols and support for BER of 10−12 and lower.","PeriodicalId":185326,"journal":{"name":"2010 IEEE Electrical Design of Advanced Package & Systems Symposium","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125363386","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}

Considering the complexity, it is very difficult to solve the whole problem directly. Even though the domain decomposition method is a legitimate approach for these types of problems, the domain decomposition method based on the equivalence principle has the low frequency breakdown issue. In this paper, we developed a low frequency augmented equivalence principle algorithm (AEPA) with the augmented electric field integral equation (AEFIE) for packaging and IC analysis. On the equivalence surfaces, not only the electric current and the magnetic current, but also the electric charge and the magnetic charge are used to capture the low frequency couplings. Inside each AEPA box, AEFIE is applied to maintain the low frequency accuracy. As a result, we are able to solve low frequency domain decomposition problems and apply it to IC packaging analysis.","PeriodicalId":185326,"journal":{"name":"2010 IEEE Electrical Design of Advanced Package & Systems Symposium","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115514731","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}
