    We propose a method to model inter-symbol interference due to temperature mismatch in the transistors of a 1-bit digital to analog converter (DAC) which is used to feedback the quantizer output in a 2nd order continuous time delta-sigma (CT/spl Delta//spl Sigma/) modulator. The degradation in the signal to noise ratio (SNR) with thermal induced inter-symbol interference is reported. The phenomenon... View full abstract»

    This work highlights the facilities of VHDL-AMS to model multi-physical systems and deal with time discontinuities. The modeling and simulation of a piezo-electric device used to spray liquids are presented. Since it is composed of several piezoelectric and metallic parts, a modular approach is proposed. A generic behavioral model for each part type - considered as a mechanical transmission line -... View full abstract»

    The investigation of neuron structures is an incredibly difficult and complex task that yields relatively low rewards in terms of information from biological forms (either animals or tissue). The structures and connectivity of even the simplest invertebrates are almost impossible to establish with standard laboratory techniques. Recent work has shown how a simplified behavioural approach to modeli... View full abstract»

    Large systems on a chip (SoC), means more functions, gates, software, engineering, cost and IP (Roberts, 2004). This increase in the digital content, coupled with the mixing of analog functionality on a single chip, and the rush to market requirements, increases the breath of complexity for the hardware and software requirements to obtain "first pass success" development cycles. For very large SoC... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (345 KB) | HTML iconHTML

    This work describes a complete framework for generation of compact analog circuit macromodels which significantly reduce the model complexity while still capturing the dominant linear and nonlinear response of the circuit. The technique is applicable to a broad class of circuits that exhibit weakly nonlinear behavior such as mixers, RF power amplifiers and switched-capacitor circuits. The Volterra...

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (177 KB) | HTML iconHTML

    This work presents a methodology, based on VHDL-AMS modeling, for taking into account the thermal effects of an optical emission module combined with electronic and optic behavior. The thermal transfer is due to the self-heating on one side and the interaction between the components of the other side. This methodology is implemented and simulated with ADVance MS/spl copy/.

    An adaptive sampling and modeling technique is presented for accurate broadband modeling of highly dynamic systems, based on a sparse set of support samples. The method is numerically more stable than conventional approaches, while desired physical properties such as system stability, causality and even passivity can be imposed. The algorithm adaptively selects a quasi-optimal sample distribution ... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (349 KB) | HTML iconHTML

    This work discusses a simulation backplane called "Simbus", which allows analog and digital simulators to be connected and utilized together to perform mixed-signal simulation. The approach allows elements of the each domain to be expressed in their native format, simulate on their native simulators, and be coupled into an aggregate mixed-signal simulation. Currently supported simulators include t... View full abstract»

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (363 KB) | HTML iconHTML

    The nature of analog and digital simulation is different, so they work with two different simulation kernels. Synchronization between these two kernels is an important challenge in the mixed signal simulation subject. In this paper we introduce an algorithm for mixed signal simulation that works based on reducing the analog and digital simulation interaction. When the simulator switches to analog ...

    A systematic synthesis methodology is introduced for the automatic design of current conveyors (CCs) and current feedback operational amplifiers (CFOAs), at the transistor level. The synthesis procedure for these active devices is executed in four steps: selection of generic cells composed of nullators/norators; addition of norators/nullators to form joined nullator-norator pairs; addition of the ...

    Verilog-A was recently enhanced to provide greater support for compact modeling. In order for Verilog-A to become the standard language for compact model development and implementation, two more steps are necessary: compact model developers must become familiar with the language, and simulators must run compact models written in Verilog-A almost as quickly and reliably as those hand-coded in C.

    This work illustrates the automatic generation of a complex semiconductor device model (BSIMSOI) into the Spectre simulator from a higher-level representation using Paragon. Paragon (Chaudharry et al., 2002) is used to capture the conceptual level description of the model and generate Verilog-AMS code. This code is used for quick turn-around model validation and subsequently used by the ADMS model... View full abstract»
