In order to relax the performance requirement of such device, the transmitter (TX) leakage needs to be suppressed. The state-of-the-art solutions failed to provide a wideband solution for cancelling the TX leakage at RF frequency, due to the lack of delay optimization. Aiming to provide high delay estimation accuracy, this paper presents a modelling technique which is based on the compressed sampling matching pursuit (CoSaMP) algorithm for compressed sampling (CS). As a result, by using the proposed modelling technique, cancellation systems, particularly the ones that are based on the analog finite impulse response (FIR) filter structure, can be implemented to achieve wideband suppressing at RF frequencies.","PeriodicalId":441203,"journal":{"name":"2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125173163","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 power-down synthesis task comprises the structural synthesis of the power-down circuitry and switch sizing. A first approach for automatic structural synthesis was published recently. This paper completes the power-down synthesis task by an effective, efficient and very easy sizing heuristic. An optimum size for the power-down switches is identified. The sizing approach is derived from exhaustive simulation results for three different amplifier circuits and a voltage-controlled ring oscillator. The variations in the power-on performance values, the power consumption during power-down mode, the power-on to power-down settling time and the power-down to power-on settling time are determined for different sizes of the power-down switches. From the simulation results, it can be concluded that the technology's minimal switch size can be chosen for the switches. This simple sizing step completes state-of-the-art power-down synthesis with the missing sizing step.","PeriodicalId":441203,"journal":{"name":"2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128816715","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}

Traditional compact EM models cannot give accurate predictions about the stress evolution over all stress conditions for complicated multi-branch interconnect structures. In this paper, we try to mitigate this problem by performing finite difference method (FDM) for the EM effects in multi-branch interconnects based on the kinetics of the first principle of EM physics. We start with the partial differential equations that describe the fundamental hydrostatic stress evolution for both the void nucleation and void growth phases with proper boundary and initial conditions for typical multi-branch metal wires: the single 2-terminal wire, and the straight-line 3-terminal wires. The new FDM for EM analysis approach can easily accommodate existing non-uniformly distributed residual stress, while existing compact EM models cannot. Time varying temperature and current, which are also difficult to model with existing methods, can also be considered with this method. Numerical results show that the proposed FDM EM analysis method agrees with the COMSOL based finite element method in terms of accuracy.","PeriodicalId":441203,"journal":{"name":"2016 13th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123945003","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 cell model's parameters (such as open-circuit-voltage and ohmic resistance) are displayed to the user as functions of state of charge, providing a visual understanding of the cell's characteristics. The GUI is also able to simulate the performance of a full battery pack consisting of a specified number of single cells using standard driving cycles and a generic electric vehicle model. After a simulation, the battery designer is able to see how well the vehicle would be able to follow the driving cycle using the tested cells. Although the GUI is developed for an automotive application, it could be extended to other applications as well.

Previous studies on compact OFET modeling have only considered static I-V characteristics, which are subject to the bias-stress effect. In this study, for the first time, two different large-signal OFET models are optimized to small-signal experimental data, which are less sensitive to the bias-stress effect. Li's and Estrada's models are studied overall I-V regions, from sub-threshold to above-threshold, and from linear to saturation region with unified formulations. It is found that Estrada's model fits better to the trans-conductance, whereas the Li's model fits better to the intrinsic gain. Both models are implemented in ADS circuit simulator, using the Verilog-A programming language.
