In this paper, we analyze the factors affecting the generation and propagation of digital SET pulses in fast CMOS ICs. Our mixed-mode simulations of various ion strike locations allowed to obtain agreement with measured data and explain the earlier published wide distribution of SET pulse widths created by heavy ion radiation in digital CMOS ICs at a given linear energy transfer (LET) value, which was observed experimentally, but not fully understood. We also indicate that the transient charge-collection current pulse (width and shape) on the struck device node is not directly related to the SET voltage pulse that will propagate through a logic circuit, and therefore current pulses alone should not be treated as a measure of DSET.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116522613","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 results show that neural network can be a good tool in modeling process of nonlinear components used in RF circuits.

In the paper a fully asynchronous multiplexer with limited hierarchical de-randomization mechanism has been presented. The hierarchical mechanism prevents collisions in the system, which occur when two or more channels attempts to connect to the output stage. The proposed mechanism enables sequential reading out each of them eliminating that potential collision problem. The results presented in this paper are shown for the case of eight input channels, however the proposed technique can be easily extended to an arbitrary large number of channels. The circuit consumes 15 muW at the power supply of 0.7 V, enabling data processing (detection + readout) with 20 MHz frequency resulting in 1 pJ energy used to detect one channel. While in a stand-by mode the circuit dissipates 2 nW.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125256148","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 unified model formulation makes it easy to handle different device structures with different physical solutions, avoiding the need to solve the different fundamental equations. It is shown that it is viable to obtain a unified solution formulation scalable with silicon layer thickness and gate oxide layer in all bias ranges, e.g. from the sub-threshold to the strong inversion and from the linear to the saturation region for the DG and SRG MOSFETs by the means of the appropriate parameter transformation. In particular, the unique physics effect of the non-classical MOS devices such as the \"volume inversion effect\" in the DG MOSFETs is exactly reproduced by present unified model with the SRG MOSFET model formulation.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130895170","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}

Despite a lot of work on biometric people recognition methods, especially those based on the iris pattern, which is the subject of the author's research, there is still room for designing a new, optimal method, e.g. one that would be simpler in computation, have a shorter iris signature and good distinctiveness. In the paper the author proposes some iris database analyses (e.g. spatial entropy and average image analyses) in order to find input images parameters helpful for designing an iris recognition method. Then, a new iris features extractor based on reverse biorthogonal wavelet rbio3.1 is proposed, which is simple in computation, has a shorter iris signature (340 bits) and quite good discriminative power (d'=6.3, EER=0,6%) in comparison with Daugman's method used as reference.
