This paper analyses the electrical characteristics of 10 nm tri-gate (TG) N- and P-channel silicon-on-insulator (SOI) FinFETs with hafnium oxide gate dielectric. The analysis has been performed through simulations by using Silvaco ATLAS TCAD with the Bohm quantum potential (BQP) algorithm. The influence of the geometrical parameters on the threshold voltage VTH, the subthreshold swing (SS), the transconductance and the on/off current ratio, ION/IOFF, is investigated. The two structures have been optimized for CMOS inverter implementation. The simulation results show that the N-FinFET and the P-FinFET can reach a minimum SS value with Fin heights of 15 nm and 9 nm, respectively. In addition, low threshold voltages of 0.61 V and 0.27 V for N- and P-channel SOI FinFETs, respectively, are obtained at a Fin width of 7 nm.

Lighting is one of the dominant electricity demand factors in the building energy sector and has huge potential for demand reduction. However, concerning the efficacy of energy consumption, this potential energy-saving option entails further investigations, particularly for developing countries. This study addresses the issues of an efficient lighting system design for educational institutions with particular attention to classroom and laboratory lighting systems for a university in Bangladesh as a case study. Measurements show that during the daytime, under clear and average sky conditions both rooms received sufficient natural light (>300 lx) for educational activities, whereas under an overcast sky, only 50% space receives sufficient natural light. At night, the installed fluorescent tube lights illuminance level was found insufficient (<300 lx) for educational activities. The inefficient lighting system design was found to be the main reason for this illuminance level. Simulation results reveal that light emitting diode (LED) tube lights with a maintenance factor of 0.8 could save 10,080-15,120 kWh, 91,929-137,894 BDT (1USD=84BDT), and 6,753-10,130 kgCO2-eq, energy, cost, and, greenhouse gas emissions respectively per year for the classrooms.

Analog buffer amplifier configurations capable of driving heavy resistive load using different operational transconductance amplifier (OTA) are presented in this paper. The OTA CMOS buffer configurations are designed using 0.18 ?m SCL technology library in Cadence Virtuoso tool and multigate transistor OTA buffer in TCAD Sentaurus tool. CMOS OTA buffer configuration using simple OTA outperform the OTA buffer circuits using other OTAs in terms of power dissipation and stability. Measured results show that the OTA buffer circuit works well for resistive load below 100 ?. The gain tuning of up to 5 V/V is achieved with RL equal to 50 ?, output swing of 1 V. OTA buffer configuration implemented using multigate transistor with resistive load below 1 k? exhibits a bandwidth around 5 GHz and tunable gain up to 5 V/V.

This paper presents a comparative analysis of solar energy potential for six different cities, in six different countries in Europe: Freiburg (Germany), Graz (Austria), Maribor (Slovenia), Banja Luka (Bosnia and Herzegovina), Nis (Serbia), and Athens (Greece). Data processed in this work are accessed from Photovoltaic Geographical Information System (PVGIS). Photovoltaic technology is crystalline silicon, and installed peak photovoltaic power is 5 kWp. The aim of the work is to find out whether there are statistically significant differences among the cities in relation to monthly energy production in regard to different types of photovoltaic system (fixed - free standing, fixed - building integrated, inclined, and two axis solar power plants). The work is based on four hypotheses. The estimation of solar energy production in different regions is very important for determination of potential regions suitable for generation of renewable and sustainable energy.

This paper proposed a fully MOS-based voltage-controlled oscillator (VCO) with tuning range and low phase noise, replacing the most often used NMOS-based inductor-capacitor tank arranged in cross-coupled topology with a high-Q active inductor. This study mainly focuses on VCO design using a MOS-based active inductor and is implemented and verified using UMC 180nm CMOS technology. The proposed VCO is resistorless and consists of an active inductor, two MOS capacitors, and the buffer circuits. The fundamental principle of this MOS-based VCO concept is to use MOS based inductor to replace the passive inductor, which is an active inductor that gives less area and low power usage. At 1 MHz frequency offset, the phase noise achieved by this proposed configuration is -102.78dBc/Hz. In the proposed VCO architecture, the frequency tuning range is 0.5GHz to 1.7GHz. This VCO design can accomplish this acceptable tuning range by altering the regulating voltage from 0.7V to 1.8V. This suggested architecture of proposed VCO design has the power consumption of 9mW with a 1.8V supply voltage. The suggested VCO has been shown to be a good fit for low-power RF circuit applications while preserving acceptable performance metrics.

The design of microstrip coupled resonator filters includes determination of the coupling coefficients between the filter resonator units. In this paper a novel modeling procedure exploiting prior knowledge neural approach is proposed as an efficient alternative to the standard electromagnetic (EM) simulations and to the neural models based purely on the artificial neural networks (ANNs). It has similar accuracy as the EM simulations and requires less training data and less time needed for the model development than the models based purely on ANNs.

The paper discusses the problem of the energy losses reduction in electrical networks using a battery energy storage system. One of the main research interests is to define the optimal battery location and control, for the given battery characteristics (battery size, maximum charge / discharge power, discharge depth, etc.), network configuration, network load, and daily load diagram. Battery management involves determining the state of the battery over one period (whether charging or discharging) and with what power it operates. Optimization techniques were used, which were applied to the model described in the paper. The model consists of a fitness function and a constraint. The fitness function is the dependence of the power losses in the network on the current battery power, and it is suggested that the function be fit by a n - order power function. The constraints apply to the very characteristics of the battery for storing electricity. At any time interval, the maximum power that the battery can receive or inject must be met. At any time, the stored energy in the battery must not exceed certain limits. The power of losses in the network is represented as the power of injection into the nodes of the network. The optimization problem was successfully solved by applying a genetic algorithm (GA), when determining optimal battery management. Finally, the optimal battery management algorithm is implemented on the test network. The results of the simulations are presented and discussed.

More efficient usage of limited energy resources on embedded platforms, found in various IoT applications, is identified as a universal challenge in designing such devices and systems. Although many power management techniques for control and optimization of device power consumption have been introduced at the hardware and software level, only few of them are addressing device operation at the application level. In this paper, a software engineering approach for managing the operation of IoT edge devices is presented. This approach involves a set of the application-level software parameters that affect consumption of the IoT device and its real-time behavior. To investigate and illustrate the impact of the introduced parameters on the device performance and its energy footprint, we utilize a custom-built simulation environment. The simulation results obtained from analyzing simplified data producer-consumer configuration of IoT edge tier, under push-based communication model, confirm that careful tuning of the identified set of parameters can lead to more energy efficient IoT end-device operation.

The goal of this work is to provide an overview about the current development of radio-frequency microelectromechanical systems technology, with special attention towards those passive components bearing significant application potential in the currently developing 5G paradigm. Due to the required capabilities of such communication standard in terms of high data rates, extended allocated spectrum, use of massive MIMO (Multiple- Input-Multiple-Output) systems, beam steering and beam forming, the focus will be on devices like switches, phase shifters, attenuators, filters, and their packaging/integration. For each of the previous topics, several valuable contributions appeared in the last decade, underlining the improvements produced in the state of the art and the chance for RFMEMS technology to play a prominent role in the actual implementation of the 5G infrastructure.
