Abstract: The article deals with BB-SPICE (SPICE for Biochemical and Biological Systems), an extension of the famous Simulation Program with Integrated Circuit Emphasis (SPICE). BB-SPICE environment is composed of three modules: a new textual and compact description formalism for biological systems, a converter that handles this description and generates the SPICE netlist of the equivalent electronic circuit and NGSPICE which is an open-source SPICE simulator. In addition, the environment provides back and forth interfaces with SBML (System Biology Markup Language), a very common description language used in systems biology. BB-SPICE has been developed in order to bridge the gap between the simulation of biological systems on the one hand and electronics circuits on the other hand. Thus, it is suitable for applications at the interface between both domains, such as development of design tools for synthetic biology and for the virtual prototyping of biosensors and lab-on-chip. Simulation results obtained with BB-SPICE and COPASI (an open-source software used for the simulation of biochemical systems) have been compared on a benchmark of models commonly used in systems biology. Results are in accordance from a quantitative viewpoint but BB-SPICE outclasses COPASI by 1 to 3 orders of magnitude regarding the computation time. Moreover, as our software is based on NGSPICE, it could take profit of incoming updates such as the GPU implementation, of the coupling with powerful analysis and verification tools or of the integration in design automation tools (synthetic biology).

Germany’s RWTH Aachen University and AMO launch joint Aachen Graphene & 2D-Materials Center

RWTH Aachen University and AMO GmbH in Germany have launched a new joint research center with a focus on efficiently bridging the gap between fundamental science and applications within graphene and related materials-based electronics and photonics.
Sharing the vision of bringing graphene and related materials research from the lab into applications, the five founding principal investigators of the Aachen Graphene and 2D-Materials Center (who are also all members of the EU-funded Graphene Flagship project) are professor Christoph Stampfer (of RWTH, and spokesman for the center), professor Max Lemme (of AMO and RWTH), professor Markus Morgenstern (of RWTH), professor Renato Negra (of RWTH) and Dr Daniel Neumaier (of AMO).
“The center will help to turn the exciting properties of graphene and 2D [two-dimensional] materials into true functions, making these materials not only fascinating for scientists but also serving society,” said Christoph Stampfer following the center’s kick-off meeting on 24 July. “With the Aachen Graphene and 2D-Material Center, we aim at increasing the visibility of Aachen as an excellent place to undertake graphene and 2D material research with both a fundamental and applied focus.”
The center enables the integration of the already ongoing work from RWTH Aachen University and AMO under a legal framework that allows for full collaboration between the groups. In particular, the center will focus on addressing the challenges of future technology including high-frequency electronics, flexible electronics, energy-efficient sensing, photonics as well as spintronics and valleytronics with graphene and related materials and their heterostructures.
Founding Members of the Aachen Graphene and 2D Materials Center:
  • Prof. Christoph Stampfer, RWTH Aachen University (Spokesman)
  • Prof. Max Lemme, RWTH Aachen University/AMO GmbH

doi: 10.1109/NEWCAS.2017.8010146

Abstract: In this work, an improved version of the basic structure of a compact MOSFET model and the respective parameters extraction methodology are proposed. The aim of this approach is to increase accuracy in hand calculations for analog circuit design without significantly increasing its complexity. The influences of both inversion level and channel length are considered in the modeling of a few features such as mobility, threshold voltage and onset of saturation. Simple design examples of current sinks and sources are accomplished to compare the basic and the improved models [read more...]

Compact Electro-Mechanical-Fluidic Model for Actuated Fluid Flow System

M. Miura-Mattausch, Fellow, IEEE, and H. J. Mattausch, Senior Member, IEEE
in IEEE Journal on Multiscale and Multiphysics Computational Techniques, 
vol. 2, no. , pp. 124-133, 2017.
doi: 10.1109/JMMCT.2017.2731878

Abstract: This paper presents a compact electro-mechanical-fluidic system-modeling method for multidomain system simulation based on multidomain physics that considers the total energy conservation condition, in terms of respective potential and flow quantities. Models for electrical, mechanical, and fluidic domains are developed to design the example of a blood pumping system, where the blood flow is driven by electrically controlled organic actuators. The electrical domain includes an organic mosfet-based control circuit, the mechanical domain includes organic actuators, and the fluidic domain includes a flexible fluid-flow channel. Control circuit, actuators, and fluid models are coupled through equivalent circuits, where interconnection relationships between two neighboring domains are expressed using the energy conservation concept. The model accuracy is verified with finite element method (FEM) based numerical simulation. Significantly faster simulation speed than with FEM and good accuracy were achieved [read more...]

Abstract: The physical influence of temperature down to the cryogenic regime is analyzed in a comprehensive study and the comparison of IV and III-V Schottky barrier (SB) double-gate MOSFETs. The exploration is done using the Synopsys TCAD Sentaurus device simulator and first benchmarked with experimental data. The important device physics of both SB-MOSFETs and conventional MOSFETs are reviewed. The impact of temperature on device performance down to the liquid-nitrogen regime is then explored. We find reduced drive currents in SB-MOSFETs fabricated on small effective mass materials and that SB lowering can significantly improve SB-MOSFETs, especially at low temperatures [read more...]

[paper] Circuit-level simulation methodology for Random Telegraph Noise by using Verilog-AMS

Circuit-level simulation methodology for Random Telegraph Noise by using Verilog-AMS
2017 IEEE ICICDT, Austin, TX, USA, 2017, pp. 1-4.
doi: 10.1109/ICICDT.2017.7993526

Abstract: As device sizes are downscaled to nanometer, Random Telegraph Noise (RTN) becomes dominant. It is indespensable to accurately estimate the effect of RTN. We propose the RTN simulation method for analog circuits. It is based on the charge trapping model. We replicate the RTN-induced threshold voltage fluctuation to attach a variable DC voltage source to the gate of MOSFET by using Verilog-AMS. We confirm that drain current of MOSFETs temporally fluctuates. The fluctuations of RTN are different for each MOSFET. Our proposed method can be applied to estimate the temporal impact of RTN including multiple transistors. We can successfully replicate RTN-induced frequency fluctuations in 3-stage ring oscillators as similar as the measurement results [read more...]
