Abstract

This paper investigates the effect of the work function on 45 nm gate length, cylindrical gate all around MOSFET and evaluates the short channel performance of the device using gate electrode work function analysis. In this work, the sensitivity of gate work function (φM) on various performance metrics like threshold voltage (Vt ), On current (ION ), subthreshold leakage current (IOFF ), On-Off current ratio (ION /IOFF ), Subthreshold slope and DIBL (Drain Induced Barrier Lowering) of cylindrical GAA are systematically evaluated and analysed. The SCE (Short Channel Effects) can sensibly be controlled and improved by proper adjustment of the metal gate work-function. In the present study, all the device performances are investigated through ATLAS device simulator from Silvaco.

Abstract

Most of the time people face problems, while navigating to a desired location of their choice in an unknown area. In order to help the people (pedestrians) from such a dilemma situation, an effective user friendly method was proposed by designing the technology in such a way that a developed system can help/ guide the visitors with the proper instructions either by playing audio route information or route map display (Azuma, 1997). The system is developed to behave as an intelligent Robot. This system could be used mainly in shopping malls, colleges, hospitals, museums, and industries for a simple and easy approaching method for Human-Robot Interaction (HRI). The Indoor Navigation Robot (INR) is developed by considering the college point of view, where a new visitor can find respective departments, canteen, library, etc. The Robot recognizes the input voice command with the help of Voice Module. The guidance for visitors will be done in two methods. The first method uses audio player which consists of Voice Recognition Module and Audio Player Recorder; both utilize the predefined voice data for their operation. The second method uses route map display, which is achieved by interfacing the Robot to MATLAB software tool on computer with the help of wireless technology (ZigBee module). The Indoor Navigation Robot has an advanced feature for security, which captures the new visitors' face and stores the captured images into database for further process. The Image will be stored in hard disc of system/Laptop. The stored image can be retrieved as and when required. The Robot has a flexible feature for displaying flash news, alert messages, and greeting messages on LCD screen through ZigBee module (10 m). This flexible feature of Robot allows the administrator to update the new information as and when required on LCD screen. The Robot takes in voice commands from the visitors and navigates by giving voice commands as well as by displaying the route map on the laptop screen, and moves with the visitor to the desired destination. This research work is useful for people who are unable to understand new location and bounded surroundings.

Abstract

In this modern era, people have succeeded in developing machineries and complex equipments, which work without any human intervention. Though these machines are very expensive they are perfectly capable of working continuously for days together which increases the productivity as well as maintain consistency in the manufacturing industries. This also reduces human effort as well as decreases the manpower required in manufacturing units. The only concern in using these expensive machineries is that it requires proper maintenance. In this paper, the authors have made an attempt to monitor and control industrial equipments remotely by developing an Internet of Things (IoT) device, which is capable of extracting the real time data, such as temperature, pressure, voltage, etc., depending on the equipments and its complexities. This device is enriched with sensors and communication protocols which makes it easier to extract the data as well as send the data to different means, such as web server applications, mobile applications, normal text messages from which the user can view the data. Also user can send data to this device and control the equipments remotely. This device is very compact, easily portable and at the same time it is very accurate, efficient, reliable and economical. With all these capabilities in a single device it can be assured that it has vast application in manufacturing and automobile industries.

Abstract

In today's world, servo motor based human artificial arm plays a very important role. These arms are used in places where it is difficult to reach mannually. It is specially used in places where the repetition of same work with same steps is happens. In this paper, the authors propose a servo motor based artificial arm that reduce much of the human efforts. This arm can be used as a replica version of natural hands. The main aim of this work is to add inputs from the virtual world to this artificial arm, and make it interact with the real world.

Abstract

In this paper, the concentration of halo implant and threshold implant has been varied to estimate the sub-threshold leakage current and substrate current of the MOSFET. A lightly doped NMOS has been designed having channel length of 40 nm in Athena and simulated in Atlas of Silvaco TCAD tool. After simulation results, it has been observed that as the threshold implant and halo implant concentrations are increased, there is a decrease in both off-state sub-threshold leakage and substrate current as required for an ideal MOSFET. Other parameters like ON current, DIBL, and threshold voltage have also been estimated.

Abstract

In today's tech-savvy world, there are several systems that continuously monitors the surrounding environment Temperature, Humidity, or any other parameter and uploads this monitored data onto the Internet. Here, the authors have developed a reliable, efficient, and cost-effective system which enables user to continuously monitor their surrounding environment parameters like Temperature, Humidity, Light Intensity, Proximity to other objects from the Sensor's position etc, by being anywhere in the world. These parameters are continuously monitored and uploaded to the internet through wireless transmission using ESP8266 WI-FI Module combined with Arduino with the help of a program. After that, the results can be viewed from ThingSpeak, which is one of the applications of Internet of Things (IoT).

Abstract

Signal integrity is becoming more and more challenging as technology changes scales down in the direction of Deep Sub Micron (DSM) technology. Interconnects are now considered the bottleneck in the design of Integrated Circuits. In the DSM technology, a coupling capacitance between interconnects is the dominant factor in the total wire capacitance. The coupling effect (capacitance formation) dominates the consumption of energy in the run-instant on the chip bus. The present survey paper with an object is to provide an overview of various approaches of encoding to reduce the coupling capacitance effect for focusing on the coding scheme to reduce switching activities on the bus. These encoding techniques are mainly memory based, degree of encoding adaptability, the amount of extra information needed for coding the targeted capacitance for switching reduction and the method for the implementation of encoding.
