This paper addresses the issue of fault modeling and mapping between a design done at the CMOS gate-level and one done using QCA technology. Since QCA and CMOS gate-level defects differ completely, it is important to investigate the mapping between classical single stuck-at fault (SSF) modeling and QCA defect and failure modes. This paper suggests a methodology in which fault modeling for a QCA circuit...
Digital Microfluidic Biochips (DMFB) is modernizing many areas of Microelectronics, Biochemistry, and Biomedical sciences. As an alternative for laboratory experiments it is popularly also known as ‘Lab-on-a-Chip’. Reduction in pin count and avoiding cross contamination are some of the important design issues for realistic relevance. These days, due to urgent situation and cost efficacy, more than...
This paper presents a microstructure optical fiber based on an octagonal structure for dispersion compensation in a wide range of wavelengths. It is shown theoretically that it is possible to obtain negative dispersion coefficient of − 821 ps/(nm.km) and relative dispersion slope (RDS) close to that of single mode fiber (SMF) of about 0.0036 nm−1 at 1550 nm wavelength. Besides the proposed octagonal...
The project presents the comprehensive explanation to thermoelectronics and is intended to provide the details overview of all the techniques that are used throughout this research as well as the change in behaviors of the samples due to their doping levels and nanowire lengths. As examples of practical realization of the measurement principles, the setup is for Seebeck coefficient measurements which...
A quasi 1-D quantum mechanical compact model for the gate tunneling current of the metal ate(TiN)/high-k(HfO2)/SiO2/p-Si nMOS capacitor is presented. With this model, measured gate leakage data is investigated using direct tunneling, multiphonon inelastic tunneling, and the Poole-Frenkel conduction mechanism. The thicker devices present a Poole-Frenkel like behaviour. The relative contributions of...
Proteins are responsible for health disorder, evolution of species. These tasks are carried out by forming functional modules. Each functional module possesses community structure. For identifying the functional modules, a lot of community detection or clustering algorithms are designed, but most of the algorithms suffer by either high computational time or inappropriate clustering results. We propose...
This paper articulates the factors primarily responsible for rapid growth of Captive Power Plants (CPPs) in Bangladesh. It also focuses on how natural gas has become the top energy source for these CPPs. Effects of inefficient use of natural gas and associated problems in CPPs are also discussed in brief. A detailed study on gas based captive power generation in Bangladesh may reveal some ways to...
Efficient use of energy becomes more crucial when increase in the cost of energy is observed. Since energy management is required to define the amount of consumed energy in a specific period of time, utilization of Energy Meters is essential. It is possible to measure the consumed energy by using a simple energy meter. But sometimes the limited functionality of these meters restricts their area of...
This paper represents a novel simulation approach of photovoltaic module with incremental conductance MPPT controlled buck-boost converter in simulink platform. Mathematical equations associated with the simulation process have been described with best clarity. Obtained results have been investigated to analyse the performance of the system using a SOLKAR 36 W PV module. This technique can also be...
Nowadays social media games such as games in facebook platform is one of the fastest growing and popular industries in the world. The goal of most social games is to entertain the player through the interaction among the players and the non-player characters (NPCs) within their friends or mutual friends. Thus, it is required to develop suitable NPCs that are fun to play against and the area of computational...
In this work a simple analytical accurate model for the threshold voltage of a double gate junction less field effect transistor has been proposed. The derivation of this analytical model has been performed by taking channel doping, oxide thickness, high k dielectric and channel thickness into consideration. Validity of the threshold voltage equation has been verified by device simulation.
A study is performed on extrinsic performance of graphene field effect transistor on a flexible polyimide substrate with graphene oxide gate dielectric. Using self-consistent calculation, it is shown that quantum capacitance retains a nonzero minimum at the dirac point. Excellent electron and hole mobilities and maximum on current of 137 μA are obtained for this flexible device. RF analysis has shown...
This report presents the enhancement of photocurrent of bulk heterojunction organic solar cell (OSC) using silicon nanoparticles (Si-NPs). Si-NPs were mixed homogeneously with the blend of poly(3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) polymer by sonication. The solar cell was fabricated by sandwiching Si-NPs mixed bulk-heterojunction of P3HT:PCBM blend between Indium-tin-oxide...
