[paper] Accurate diode behavioral model with reverse recovery

Volume 139, January 2018, Pages 31–38

Highlights:

  • The complex robust time and area scalable Verilog-A model of diode containing reverse recovery effect has been developed.
  • Due to implemented reverse recovery effect the model is useful especially for high-speed or high-voltage power devices.
  • The model can be used as stand-alone 2-terminal diode or as a parasitic p-n junction of more complex lumped macro-model.
  • Two methods of model parameter extraction or model validation have been demonstrated.

ABSTRACT: This paper deals with the comprehensive behavioral model of p-n junction diode containing reverse recovery effect, applicable to all standard SPICE simulators supporting Verilog-A language. The model has been successfully used in several production designs, which require its full complexity, robustness and set of tuning parameters comparable with standard compact SPICE diode model. The model is like standard compact model scalable with area and temperature and can be used as a stand-alone diode or as a part of more complex device macro-model, e.g. LDMOS, JFET, bipolar transistor. The paper briefly presents the state of the art followed by the chapter describing the model development and achieved solutions. During precise model verification some of them were found non-robust or poorly converging and replaced by more robust solutions, demonstrated in the paper. The measurement results of different technologies and different devices compared with a simulation using the new behavioral model are presented as the model validation. The comparison of model validation in time and frequency domains demonstrates that the implemented reverse recovery effect with correctly extracted parameters improves the model simulation results not only in switching from ON to OFF state, which is often published, but also its impedance/admittance frequency dependency in GHz range. Finally the model parameter extraction and the comparison with SPICE compact models containing reverse recovery effect is presented [read more...]

[paper] A Novel Reconfigurable sub-0.25V Digital Logic Family Using the Electron-Hole Bilayer TFET

Cem Alper, Jose Luis Padilla, Pierpaolo Palestri, Senior Member, IEEE
and Adrian M. Ionescu, Fellow, IEEE
IEEE Journal of the Electron Devices Society

doi: 10.1109/JEDS.2017.2758018

Abstract: We propose and validate a novel design methodology for logic circuits that exploits the conduction mechanism and the presence of two independently biased gates (”n-gate” and ”p-gate”) of the electron-hole bilayer TFET (EHBTFET). If the device is designed to conduct only under certain conditions e.g. when Vn-gate = VDD and Vp-gate = 0, it then shows an ’XOR-like’ behavior that allows the implementation of certain logic gates with a smaller number of transistors compared to conventional CMOS static logic. This simplifies the design and possibly results in faster operation due to lower node capacitances. We demonstrate the feasibility of the proposed EHBTFET logic for low supply voltage operation using mixed device/circuit simulations including quantum corrections [read more...]

[paper] Design techniques for low-voltage analog integrated circuits

Matej Rakus, Viera Stopjakova, Daniel Arbet
Institute of Electronics and Photonics, Faculty of Electrical Engineering
and Information Technology Slovak University of Technology in Bratislava, Slovakia,
Journal of ELECTRICAL ENGINEERING, Vol.68 (2017), No.4, 245–255
DOI: 10.1515/jee-2017–0036

ABSTRACT: In this paper, a review and analysis of different design techniques for (ultra) low-voltage integrated circuits (IC) are performed. This analysis shows that the most suitable design methods for low-voltage analog IC design in a standard CMOS process include techniques using bulk-driven MOS transistors, dynamic threshold MOS transistors and MOS transistors operating in weak or moderate inversion regions. The main advantage of such techniques is that there is no need for any modification of standard CMOS structure or process. Basic circuit building blocks like differential amplifiers or current mirrors designed using these approaches are able to operate with the power supply voltage of 600 mV (or even lower), which is the key feature towards integrated systems for modern portable applications.

[paper] Principles and Trends in Quantum Nano-Electronics and Nano-Magnetics for Beyond-CMOS Computing

Ian A. Young and Dmitri E. Nikonov 
Components Research, Technology & Manufacturing Group
Intel Corp., Hillsboro, Oregon, USA
ESSDERC/ESSCIRC Leuven Sept.12-14, 2017

Abstract: An analysis of research in quantum nanoelectronics and nanomagnetics for beyond CMOS devices is presented. Some device proposals and demonstrations are reviewed. Based on that, trends in this field are identified. Principles for development of competitive computing technologies are formulated. Results of beyond-CMOS circuit benchmarking are reviewed.

TABLE I: Voltage Limitations For Computation Variables

Principle 1: Beyond-CMOS circuits require CMOS as an integral part. They will work alongside and augment CMOS computing blocks.

Principle 2: Some devices utilize collective states; this confers advantages of non-volatility or more energy efficient operation.

Principle 3: The choice for an optimal beyond-CMOS device will be determined by compatibility with an efficient and effective interconnect.

Principle 4: Low voltage devices – most direct way to low energy operation.

Principle 5: Start benchmarking with bottom up modeling of devices, build up from simple to more complicated circuits.

Principle 6: Majority gates (if easily implemented in a certain technology) enable more efficient circuits, especially for more complex computation functions.

Principle 7: Use electrical interconnects for longer propagation spans.

Principle 8: To convince the wider community, a non- volatile computing paradigm needs to be general enough to prove that it is valid for more than one architecture; while it needs to be specific enough to dispel claims that an essential aspect is missed.

Principle 9: Neuromorphic computing can be done more efficiently with beyond-CMOS circuits.

Conclusions: In summary, we have presented our view on the recent trends in quantum nanoelectronics and nanomagnetics for beyond CMOS devices, and outlined a few principles to make them realize practical computing technologies. We can pose a question for ourselves: What are the most promising directions of research? Where to double down on the effort? Among many equally important thrusts, our subjective preference is for magnetoelectric switching and neuromorphic beyond-CMOS circuits.

[book] Systematic Design of Analog CMOS Circuits

Paul G. A. Jespers, Boris Murmann
Cambridge University Press; 31 Oct 2017; 342pp

Discover a fresh approach to efficient and insight-driven analog integrated circuit design in nanoscale-CMOS with this hands-on guide. Expert authors present a sizing methodology that employs SPICE-generated lookup tables, enabling close agreement between hand analysis and simulation. This enables the exploration of analog circuit tradeoffs using the gm/ID ratio as a central variable in script-based design flows, and eliminates time-consuming iterations in a circuit simulator. Supported by downloadable MATLAB code, and including over forty detailed worked examples, this book will provide professional analog circuit designers, researchers, and graduate students with the theoretical know-how and practical tools needed to acquire a systematic and re-use oriented design style for analog integrated circuits in modern CMOS.

[paper] Surface Potential Equation for Low Effective Mass Channel Common Double-Gate MOSFET

Ananda Sankar Chakraborty and Santanu Mahapatra, Senior Member, IEEE
in IEEE Transactions on Electron Devices
vol. 64, no. 4, pp. 1519-1527, April 2017
doi: 10.1109/TED.2017.2661798

Abstract: Formulation of accurate yet computationally efficient surface potential equation (SPE) is the fundamental step toward developing compact models for low effective mass channel quantum well MOSFETs. In this paper, we propose a new SPE for such devices considering multisubband electron occupancy and oxide thickness asymmetry. Unlike the previous attempts, here, we adopt purely physical modeling approaches (such as without mixing the solutions from finite and infinite potential wells or using any empirical model parameter), while preserving the mathematical complexity almost at the same level. Gate capacitances calculated from the proposed SPE are shown to be in good agreement with numerical device simulation for wide range of channel thickness, effective mass, oxide thickness asymmetry, and bias voltages [read more...]

levmar : Levenberg-Marquardt nonlinear least squares algorithms in C/C++


The site provides GPL native ANSI C implementations of the Levenberg-Marquardt optimization algorithm, usable also from C++, Matlab, Perl, Python, Haskell and Tcl and explains their use. Both unconstrained and constrained (under linear equations, inequality and box constraints) Levenberg-Marquardt variants are included. The Levenberg-Marquardt (LM) algorithm is an iterative technique that finds a local minimum of a function that is expressed as the sum of squares of nonlinear functions. It has become a standard technique for nonlinear least-squares problems and can be thought of as a combination of steepest descent and the Gauss-Newton method. When the current solution is far from the correct one, the algorithm behaves like a steepest descent method: slow, but guaranteed to converge. When the current solution is close to the correct solution, it becomes a Gauss-Newton method.

Interfaces for using levmar from high-level programming environments & languages such as Matlab, Perl Python, Haskell and Tcl are also available; please refer to the FAQ for more details.

[paper] Nanoscale MOSFET Modeling

 Nanoscale MOSFET Modeling: 
Part 1: The Simplified EKV Model for the Design of Low-Power Analog Circuits
C. Enz, F. Chicco and A. Pezzotta
in IEEE Solid-State Circuits Magazine, vol. 9, no. 3, pp. 26-35, Summer 2017
doi: 10.1109/MSSC.2017.2712318

Abstract: This article presents the simplified charge-based Enz-Krummenacher-Vittoz (EKV) [11] metal-oxide-semiconductor field-effect transistor (MOSFET) model and shows that it can be used for advanced complementary metal-oxide-semiconductor (CMOS) processes despite its very few parameters. The concept of an inversion coefficient (IC) is first introduced as an essential design parameter that replaces the overdrive voltage VG-VT0 and spans the entire range of operating points from weak via moderate to strong inversion (SI), including the effect of velocity saturation (VS). The simplified model in saturation is then presented and validated for different 40- and 28-nm bulk CMOS processes. A very simple expression of the normalized transconductance in saturation, valid from weak to SI and requiring only the VS parameter mc, is described. The normalized transconductance efficiency Gm/ID, which is a key figure-of-merit (FoM) for the design of low-power analog circuits, is then derived as a function of IC including the effect of VS. It is then successfully validated from weak to SI with data measured on a 40-nm and two 28-nm bulk CMOS processes. It is then shown that the normalized output conductance Gds/ID follows a similar dependence with IC than the normalized Gm/ID characteristic but with different parameters accounting for drain induced barrier lowering (DIBL). The methodology for extracting the few parameters from the measured ID-VG and ID-VD characteristics is then detailed. Finally, it is shown that the simplified EKV model can also be used for a fully depleted silicon on insulator (FDSOI) and Fin-FET 28-nm processes [read more...]

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.

15th IEEE NEWCAS
Strasbourg, France, 2017, pp. 225-228
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...]

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...]
