Journal of Computational Electronics, 2017, pp. 1-13

Abstract: A generic compact modeling methodology for emerging nonvolatile memories is proposed by coupling comprehensive physical equations from multiple domains (e.g., electrical, thermal, magnetic, phase transitions). This concept has been applied to three most promising emerging memory candidates: PCM, STT-MRAM, and RRAM to study their device physics as well as to evaluate their circuit-level performance. The models’ good predictability to experiments and their effectiveness in large-scale circuit simulation suggest their unique role in emerging memory research and development [read more...]

Cryogenic characterization of CMOS technologies

A. Beckers, F. Jazaeri, A. Ruffino, C. Bruschini, A. Baschirotto and C. Enz
Cryogenic characterization of 28 nm bulk CMOS technology for quantum computing
47th ESSDERC, Leuven, Belgium, 2017, pp. 62-65.

Abstract: This paper presents the first experimental investigation and physical discussion of the cryogenic behavior of a commercial 28 nm bulk CMOS technology. Here we extract the fundamental physical parameters of this technology at 300,77 and 4.2 K based on DC measurement results. The extracted values are then used to demonstrate the impact of cryogenic temperatures on the essential analog design parameters. We find that the simplified charge-based EKV model can accurately predict the cryogenic behavior. This represents a main step towards the design of analog/RF circuits integrated in an advanced bulk CMOS process and operating at cryogenic temperature for quantum computing control systems [read more...doi: 10.1109/ESSDERC.2017.8066592

Nanometer CMOS characterization and compact modeling at deep-cryogenic temperatures
47th ESSDERC, Leuven, Belgium, 2017, pp. 58-61.

Abstract: The characterization of nanometer CMOS transistors of different aspect ratios at deep-cryogenic temperatures (4 K and 100 mK) is presented for two standard CMOS technologies (40 nm and 160 nm). A detailed understanding of the device physics at those temperatures was developed and captured in an augmented MOS11/PSP model. The accuracy of the proposed model is demonstrated by matching simulations and measurements for DC and time-domain at 4 K and, for the first time, at 100 mK [read more...doi: 10.1109/ESSDERC.2017.8066591

[paper] Accurate diode behavioral model with reverse recovery

Stanislav Banáša,b, Jan Divínab, Josef Dobešb, Václav Paňkoa
aON Semiconductor, SCG Czech Design Center, Department of Design System Technology, 1. maje 2594, 756 61 Roznov pod Radhostem, Czech Republic

Volume 139, January 2018, Pages 31–38


  • 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...]
