It is found that the off-state breakdown voltage increases almost linearly with gate-to-drain spacing with the slop of about 46.8V/gm. Sentaurus software was used to find the physical mechanism of this phenomenon. By comparing the simulation results of devices with and without deep-level acceptor traps in GaN buffer layer, it is found that the deep-level acceptor traps in GaN buffer layer underneath the gate-to-drain channel could be occupied by hot electrons created in channel, which would extend the channel depletion region and then alleviate the maximum channel electric field. The theoretical and simulation analysis show that there is a positive correlation between the depletion length and the off-state gate-drain breakdown voltage. The simulation results show that with gate-to-drain spacing increasing, the negatively charged buffer traps region spread wider and the depletion region length becomes longer, playing a key role in the linear dependence of off-state gate-drain breakdown voltage on gate-to-drain spacing.","PeriodicalId":179100,"journal":{"name":"2016 International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130227717","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 analysis shows that the cut-off frequency increases as the Schottky contact area decreases. The series resistance can be further reduced by employing a four-sided cathode. The designed diode achieves the cut-off frequency of 1.3 THz. The ideality factor is 1.34, and the barrier height is 0.38 eV.

Different from conventional of focusing on load capacitance and input transition, our proposed model pay more attention to the impact of AVth variation caused by NBTI degeneration on the propagation delay. Moreover, this paper has also proposed a framework to calculate the path delay and clock skew of clock tree network based on the proposed delay model. In order to validate our proposed models and methods, the SPICE-level simulation of the benchmark circuit (s38417) has been compared with our model calculation using a 45-nm CMOS process technology, the results show that our models and methods can calculate the extra path delay and clock skew caused by the shift in threshold voltage.","PeriodicalId":179100,"journal":{"name":"2016 International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125779460","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, due to the aggressive technology scaling, following the improvement of system integration, the rise of power density increases rapidly, which causes a significant number of hot spots and poses an enormous threat to the performance and lifetime of chips. For better modulation of this problem, an accurate temperature simulation platform is urgently necessary. In this paper, based on the open-source Gem5, McPAT and Hotspot simulators, a novel simulation framework is built for accurate power and temperature simulation of Network-on-Chips. Gem5 is adopted to simulate the specified CPU model and obtained access statistics. McPAT and Hotspot are utilized to estimate the power and temperature of the corresponding architecture, respectively. Afterwards, a set of temperature-aware dynamic task scheduling algorithms are then conducted to evaluate the performance of the proposed simulation framework.","PeriodicalId":179100,"journal":{"name":"2016 International Conference on Integrated Circuits and Microsystems (ICICM)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121854522","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}
