Abstract: Digital electronics are ubiquitous in the modern world, but analogue electronics also play a crucial role in many devices and applications. Analogue circuits are typically manufactured using silicon as the active material. However, the desire for improved performance, new devices and flexible integration has—as for their digital counterparts—led to research into alternative materials, including the use of two-dimensional (2D) materials. Here, we show that operational amplifiers—a basic building block of analogue electronics—can be created using the 2D semiconductor molybdenum disulfide (MoS2) as the active material. The device is capable of stable operation with good performance, and we demonstrate its use in feedback circuits including inverting amplifiers, integrators, log amplifiers and transimpedance amplifiers. We also show that our 2D platform can be used to monolithically integrate an analogue signal preconditioning circuit with a MoS2 photodetector.

Circuit design and modelling: Because a complete model of back-gated 2D semiconductor FETs is still not readily available, we fitted the experimental results with an Enz–Krummenacher– Vittoz (EKV) model in both, the subthreshold and inversion, regimes. All the transistors operate in the inversion regime, we used the inversion model to simulate the OPA, obtaining a nominal low-frequency Atot gain value.

Abstract: A high-frequency small-signal model for a MOSFET is proposed considering the parasitic capacitances associated with each terminal that is critical in the design of high-frequency amplifiers. The proposed model allows in obtaining a closed form expression for poles and zeros due to parasitic elements along with the conventional poles and zeros. This model gives an additional degree of freedom in choosing the location of poles and zeros to improve the frequency response. The proposed high-frequency small-signal model for MOSFET is validated in simulation by implementing a high-frequency voltage follower in 0.18µm CMOS process. The proposed model shows the existence of a zero in a voltage follower that is introduced by the parasitic elements at high-frequencies and it is validated with implementation.

[paper] Vertical Graphene–hBCN Heterostructure TFETs

A comparative computational study of tunneling transistors
based on vertical graphene–hBCN heterostructures

ABSTRACT In this paper, the electrical characteristics of tunneling transistors based on vertical graphene and a hexagonal boron-carbon-nitrogen (hBCN) heterostructure are studied and compared theoretically. We have considered three different types of hBCN, i.e., BC2N, BC2N0, and BC6N as a tunneling barrier. Our simulation is based on the nonequilibrium Green’s function formalism along with an atomistic tightbinding (TB) model. The TB parameters are obtained by fitting the band structure to first-principles results. By using this method, electrical characteristics of the device, such as the ION=IOFF ratio, subthreshold swing, and intrinsic gate-delay time, are investigated. For a fair comparison, the effects of geometrical variations and number of tunneling barrier layers on the electrical parameters of the device are simulated and investigated. We show that, by an appropriate design, the device can be used for low-power or high-performance applications. The device allows current modulation exceeding 106 at room temperature for a 0.6 V bias voltage.

Abstract: In this review, recent advances in compact modeling of organic field-effect transistors (OFETs) are presented. Despite the inherent strength for printed flexible electronics and the extremely aggressive research conducted over more than three decades, the OFET technology still seems to remain at a relatively low technological readiness level. Among various possible reasons for that, the lack of a standard compact model, which effectively bridges the device- and system-level development, is clearly one of the most critical issues. This paper broadly discusses the essential requirements, up-to-date progresses, and imminent challenges for the OFET compact device modeling toward a universal, physically valid, and applicable description of this fast-developing technology.

Abstract: This letter reports on a dual-mode wearable energy harvester that utilizes both piezoelectric and photoelectric effects. It integrates a piezoelectric transducer with a 3-D photosensitive dual-gate thin-film transistor (DGTFT) as a rectifier and a buffer. The energy conversion efficiency is enhanced by reducing the internal resistance of the 3-D photosensitive DGTFT upon light illumination. Such a dual-mode energy harvester is promising for wearable electronics.

[paper] Compact Models for IGBTs

Advanced physics-based compact models for new IGBT technologies
Arnab Biswas, Maria Cotorogea
Infineon Technologies AG, Germany

Abstract The TRENCHSTOP™ IGBT7 technology is based on the latest micro-pattern trench technology. It provides strongly reduced losses offering a high level of controllability [1]. This technology brings forward new challenges in compact modelling. Current IGBT compact models at Infineon are physics-based subcircuit representations in SPICE syntax. They were developed to run in the circuit simulator SIMetrix, and are manually calibrated. The aim of this work is to present advanced models for the micro-pattern trench IGBT implemented in Verilog-A language, addressing the challenges of compact models in terms of calibration accuracy, simulation run time, model robustness and portability to multiple simulators.

[paper] Mobility in GC SOI Transistors

Lucas M. B. da Silva1, Bruna Cardoso Paz2, Michelly de Souza1
Analysis of Mobility in Graded-Channel SOI Transistors Aiming at Circuit Simulation
Journal of Integrated Circuits and Systems; vol. 15, no. 2 pp.1-5 (2020)

Abstract: This work presents an analysis of the behavior of the effective mobility of graded-channel FD SOI transistors using an Y-Function-based technique. Low field mobility, linear and quadratic attenuation factors were extracted from two-dimensional numerical simulations. The influence of the length of both channel regions over these parameters was analyzed. The parameters extracted from experimental data were used in a SPICE simulator, showing that it is possible to simulated GC SOI MOSFET using a regular SOI MOSFET model, by adjusting its parameters. This approach presents a percentage error smaller than 7.91% for low VDS.

Abstract: The unique properties of two-dimensional (2D) materials have boosted intensive interests in combining distinct 2D materials into van der Waals heterojunctions for novel device structures. The organic-inorganic heterojunctions, integrating atomically thin inorganic materials with an unlimited variety of organic molecules, provide an ideal platform for broader, superior, and on-demand functional applications by incorporating customized organic molecules that particularly exhibit decent optoelectronic properties, promising scalability and remarkable flexibility. In this Review, emerging 2D organic-inorganic heterojunctions from the perspectives of materials, manufacturing, structures, and interfaces, as well as recent progress in functional applications, are provided. Two prototypical construction approaches are summarized—epitaxy growth and molecular doping—followed by four directions of device applications, including electronic device, optoelectronic device, energy harvesting device, and memory and neuromorphic device. Finally, the frontier challenges and future outlook associated with the organic-inorganic heterojunctions are highlighted, which is critical for the further development of this cross-fertilized research field.

Abstract: Previous cryogenic electronics studies are mostly at 77K and 4.2K. Cryogenic characterization of a 0.18μm standard bulk CMOS technology (operating voltages: 1.8V and 5V) is presented in this paper. Several NMOS and PMOS devices with different width to length ratios (W/L) were extensively tested and characterized under various bias conditions at sub-kelvin temperature. In addition to devices dc characteristics, the kink effect and current overshoot phenomenon are observed and discussed at sub-kelvin temperature. Especially, the current overshoot phenomenon in PMOS devices at sub-kelvin temperature is shown for the first time. The transfer characteristics of MOSFET devices (1.8V W/L = 10μm/10μm) at sub-kelvin temperature are modeled using the simplified EKV model. This work facilitates the CMOS circuits design and the integration of CMOS circuits with silicon-based quantum chips at extremely low temperatures.

Abstract: This paper presents test-beam results of monolithic pixel detector prototypes fabricated in 200nm Silicon-On-Insulator (SOI) CMOS technology studied in the context of high spatial resolution performance. The tested detectors were fabricated on a 500µm thick highresistivity Floating Zone type n (FZ-n) wafer and on a 300 µm Double SOI Czochralski type p (DSOI Cz-p) wafer. The pixel size is 30µm×30µm and two different front-end electronics architectures were tested, a source follower and a charge-sensitive preamplifier. The test-beam data analyses were focused mainly on determination of the spatial resolution and the hit detection efficiency. In this work different cluster formation and position reconstruction methods are studied. In particular, a generalization of the standard η-correction adapted for arbitrary cluster sizes, is introduced. The obtained results give in the best case a spatial resolution of about 1.5µm for the FZ-n wafer and about 3.0µm for the DSOI Cz-p wafer, both detectors showing detection efficiency above 99.5%.

TSMC: All the Processes, All the Fabs

TSMC Technology Symposium: All the Processes, All the Fabs
by Paul McLellan at breakfast-bytes
27 Aug 2020

TSMC has new transistor structure (nanosheet) and new materials such as high mobility channel, 2D, carbon nanotube (CNT). TSMC has already demonstrated at 32Mb nanosheet SRAM fully-functional at 0.46V. It has also identified promising 2D materials such as MoS2 (molybdenum disulfide). At IEDM last year, they disclosed the first BEOL CNT power-gating device integrated with silicon-based CMOS.
Scaling continues with EUV advances with the current generation of scanners. They are also working with ASML (the only supplier of EUV equipment) on High-NA EUV [read more...]

Chip in the Fields: SBCCI and SBMicro Conferences

Chip in the Fields
C̶a̶m̶p̶i̶n̶a̶s̶,̶ ̶S̶P̶,̶ ̶B̶r̶a̶z̶i̶l̶ ̶ 
Virtual
August 24 to 28, 2020

Due to the COVID-19 pandemic the Chip in the Fields is changed to a virtual event. In 2021 we plan to have again the normal live Chip in the Fields events to be held in Hotel Premium, Campinas, SP, Brazil

The conferences SBCCI and SBMicro started in the early 80’s and since the year 2000 they joined forces, organizing them at the same venue and under a unified fantasy name “Chip in Somewhere”. The somewhere could be the name of the city or a fantasy name related to the region. It started with the name of “Chip in the Jungle”, because it was held in Manaus, the heart of the Amazon forest. 

Along these 21 years of Chip in, gradually other conferences joined the common venue and organization. Nowadays, we are composed of five sister conferences: SBCCI, SBMicro, WCAS, INSCIT and Sforum, as described in the respective call for papers. Due to the COVID-19 pandemic the Chip in the Fields is changed to a virtual event. Detalhes of the program and access link will be made available in the near future. Please follow the conference website for future up-dates.
