The $mathrm{g}_{mathrm{m}}/mathrm{I}_{mathrm{D}}$ methodology is applicable for the circuit design in advanced nanometer technologies. This work proposes a systematic parameter extraction process for a simplified EKV-model with only three model parameters which is applicable to all CMOS technologies. The extraction procedure relies only on the drain current for a sweep of the gate voltage without the need of additional extraction simulations in SPICE or parameters from the model card. Therefore, it is independent from the applied technology or the compact model of the SPICE simulation. For devices with short channel lengths, three variations of the EKV model were evaluated which consider velocity saturation. The resulting model provides good results compared to the SPICE simulation over the complete operation region of the technology for long and short channel devices while keeping simplicity for fast tool-based circuit design procedures and hand calculations.

We evaluate the subband structure in a narrow nanoribbon of 1T’ molybdenum disulfide by employing an effective $mathrm{k}cdot mathrm{p}$ Hamiltonian. Highly conductive topologically protected edge states whose energies lie within the bulk band gap are investigated. Due to the interaction of the edge modes located at the opposite edges, a small gap in their linear spectrum opens in a narrow nanoribbon. This gap is shown to sharply increase with the perpendicular out-of-plane electric field, in contrast to the behavior in a wide nanoribbon. The gaps between the electron and hole bulk subbands also increase with the electric field. The increase of the gaps between the subbands leads to a rapid decrease of the ballistic nanoribbon conductance and current with the gate voltage, which can be used for designing molybdenum disulfide nanoribbon-based current switches.

While the development of lab-on-chip is increasing, the lack of dedicated computer-aided design tools appears as a bottleneck preventing the emergence of large-scale industrial applications. One of the answer relied on 50 years of CAD experience in microelectronic. Based on this fact, and using this environment, multi-domain libraries (fluidic, biological, chemical) are to be designed. Among other, the development of efficient compact model for microfluidic devices is a first step toward such design tool. This paper deals with a continuous microfluidic mixer. Our model takes as inputs the flow rates and the concentrations of each fluid to mix and returns the flow rate and the concentration profiles across the channel at its output. The model depends also on some physical parameters (e.g. diffusion coefficient of fluids) and mixing channel geometry. The model is validated by comparison with finite-element simulation performed with COMSOL Multiphysics. Comparisons are made on several cases. We demonstrated that the model gives a good estimation of the concentration profile, with an error of less than 2% compared to the finite element simulator.

Authors presents a very important problem of estimation capacitance structures used in MEMS sensors. The importance comes from the fact that during operation, inertial sensors deform under influence of external forces. The result of the problem is visible in capacitance deviations what directly may be seen in accuracy sensor measurement.

Many emerging organic semiconductor devices suffer from hysteresis effects caused by traps. The impact of such traps on AC device performance has not been investigated yet. In this paper, high-frequency non-quasi-static effects related to dynamic trapping based on a theoretical framework, TCAD simulations and experimental data have been studied. In contrast to previous studies, the focus of this paper is the OFET's high-frequency performance and not the characterization of the traps.

The paper presents the Linux kernel driver for analog-to-digital and digital-to-analog converters control. The proposed module is the main part of the distributed embedded system for impedance measuring applications. The designed prototype consists of three hardware components: Raspberry Pi 3, microcontroller and personal computer. Two experiments verified the functionality and parameters of the constructed system. The first one confirmed that the driver does not utilize processor time while the data processing application is not running. It also showed that the module consumes only 0.7 % and 3.3 % of two cores of a quad-core processor for data readout and its copying to the user space. The mentioned test was performed with the sampling frequency equal to 256 kHz. The second experiment determined the accuracy of impedance measurements done by the constructed prototype. Results were compared with ones realized with the commercially available measuring device usage. The determined measurements uncertainty did not exceed 1.5 %.

Autonomous mobile vehicles need advanced systems to determine their exact position in a certain coordinate system. For this purpose, the GPS and the vision system are the most often used. These systems have some disadvantages, and so the GPS signal is unavailable in rooms and may be inaccurate, while the vision system is strongly dependent on the intensity of the recorded light. This work presents a system for determining the position of the robot base on information about the distance travelled coming from each vehicle wheel and the IMU sensor. However, wheels odometry introduces an additive measurement error (rise in every measure cycle). In this work there has been a vision correction system applied, where corrections are calculated by measuring the distance to artificial markers. This system precisely determines such correction. Each of these systems is described in the paper, in particular the vision system. There is also a description of a fusion algorithm of wheels odometry and vision correction system. The presented system was tested on an artificially built test track.
