DL Talk 3: 5.00PM to 5.45 PM Speaker: Prof. Roberto Murphy, INAOE (Mexico)
Topic: Fundamental Aspects of CMOS RF Modeling and Characterization
As CMOS technology evolves, higher frequencies can be attained while more complex functions and operations become possible in Integrated Circuits. At the design stage, there are several fundamental aspects which have to be taken into account in order to have successful fabrication results, the closest to simulation predictions as possible. Furthermore, this evolution leads to more time-consuming characterization routines, which require both personnel and time to be performed. Some of the aspects dealt with in this talk refer to characterization techniques, substrate network effects, and geometry effects.

Multiphysics Simulation of Biosensors

M. Madec, L. Hébrard, J. Kammerer, A. Bonament, E. Rosati and C. Lallement
Multiphysics Simulation of Biosensors Involving 3D Biological Reaction-Diffusion Phenomena in a Standard Circuit EDA Environmen
IEEE Transactions on Circuits and Systems I: Regular Papers.
doi: 10.1109/TCSI.2018.2885223

Abstract: The topic of this paper is the development of biological models for 3D reaction-diffusion phenomena that can be used in any circuit electronic design automation environment for the simulation of biosensors. Biological systems that involve such 3D phenomena are described by partial differential equations. Our approach consists in discretizing these equations according to the finite-difference method and converting the resulting ordinary differential equations into an assembly of elementary electronic equivalent circuits that are directly simulated with SPICE. The main interest of this approach is the ability to couple such models with third-party SPICE models of electronic circuits, sensors, and transducers, i.e., models from any physical domain ruled by Kirchhoff laws, allowing modeling and simulation of any multi-physics systems in a conventional circuit design environment, here CADENCE. The tool is validated on simple problems for which analytical solutions are known. Then, the interest of the approach is illustrated on the study of a biosensor.

An Empirical Model to Enhance the Flexibility of gm/Id Tuning in BSIM-BULK Model

Ravi Goel, Chetan Gupta, Yogesh S. Chauhan
EE Department, Indian Institute of Technology Kanpur, Kanpur, India
Published in: 2018 5th IEEE Uttar Pradesh Section International Conference on Electrical, Electronics and Computer Engineering (UPCON)

Abstract: Recent enhancement in BSIM-BULK (formerly BSIM6) model is presented in this work. The industry standard models like BSIM4, PSP, BSIM-BULK etc. lack the parameters for tuning of transconductance to channel current ratio (gm/Id). gm/Id is also a critical figure of merit for analog applications. Here, we propose an empirical model to enhance the flexibility of gm/Id tuning behavior. The proposed model provides good fitting for different channel lengths and drain bias.

Paper Sections:
I. Introduction
II. An Empirical Model for gm/Id Tuning
III. Model Implementation
IV. Model Validation with TCAD
V. Conclusion

Compact Transcapacitance Model for Short Channel DG FinFETs

(Proceedings of the Int. Conference on Microwave and THz Technologies and Wireless Comm.)
Ashkhen Yesayan
Institute of Radiophysics and Electronics
Alikhanian Brothers str. 1, 0203 Ashtarak, Armenia
Received 15 November 2018

Abstract: A compact capacitance model is developed accounting for small-geometry effects in FinFETs. While decreasing the channel length, the transcapacitance model becomes very sensitive to all short channel effects, both in moderate and strong inversion regimes. In addition, for short channel devices, we need to take into account the inter-electrode capacitive coupling in the subthreshold regime, which is not significant for long channel devices. The quantum mechanical effects, which are very significant for thin Fins, are included in the model. The effect of mobility degradation on C-V characteristics is also demonstrated. The model was validated with numerical 3D Atlas simulations and a good accuracy of the model has been demonstrated in all operating regimes.

Therefore, a new Special Issue was needed that could include high-quality papers in these topics.

A total of 60 regular papers were submitted to this Special Issue, of which 21 were accepted. Besides, the Special Issue includes four invited papers. All papers, including the invited ones, were subjected to thorough peer review. A high number of reviewers have participated in this process. This has resulted in a Special Issue containing very high-quality papers.

The published papers target compact modeling aspects for a wide number of devices: several MOSFET structures, tunnel FETs, HEMTs, nanowire FETs, TMD FETs, TFTs, OLEDs, solar cells, photodiodes, and so on.Besides, different operation regimes and analyses are addressed: dc, RF, HV, ballistic regime, variability, reliability, aging, and so on.

The four invited papers also target different topics. The paper by C. C. McAndrew is focused on the successes and challenges of MOS compact models. S. Dongaonkar et al. address the opportunities and challenges of circuit design methodologies ranging from process corners to statistical circuit design. P. Zampardi et al. discuss the industrial view of III–V device compact modeling for circuit design. Finally, Madec et al. target a quite different and challenging environment for the modeling of biosensors, biosystems, and lab-on-chips.

I would like to thank the work done by the rest of the Editors of this Special Issue and also by all the reviewers who participated in this process. And of course, I want to thank all the authors for their interest in submitting papers to this Special Issue. Thanks to authors, reviewers, and editors, this high-quality Special Issue has been possible.
