In this paper, the performance of a novel n-type dielectric modulated gate engineered asymmetric dual short gate tunnel field effect transistor (ADSG-TFET) with pocket doping at the channel region is analyzed and presented. The effects of different high-k materials, silicon film thickness are investigated. The device characteristics are compared with conventional asymmetric structure with and without...
The development in the field of sensors in general and biosensors in particular has motivated the research in the recent past. The design and fabrication of devices for health care monitoring has drawn attention in the twenty first century. The simulation of the high-k dielectric (HfO2) FinFET biosensor with nano dimension has been carried out and presented in the present paper. Based on the existing...
Accidents at the unmanned railway crossings have always been a matter concern all around the world. This concern is further increased in India, due to its large population of the unmanned railroad crossings. Almost 40% of the level crossings present in India are unmanned. Hence this calls for an efficient, robust and stable automatic gate closure system. This paper proposes an intelligent level crossing...
In recent years wireless sensor networks are widely used in many automated system like vehicle monitoring, heavy duty plants, robotic control etc. one of the best automated systems is the smart irrigation system. In this paper we have proposed a simple and cost effective smart irrigation system. Our system deploys wireless sensor motes from a wireless sensor network. The system is modelled in outdoor...
This paper proposes the hardware design and implementation of a Microcontroller based single-phase simplified seven-level inverter for PV system. Multilevel inverters tender high power capability, associated with lower output harmonics and lower turn-off losses. This work informs a multilevel inverter for PV system using an H-bridge output stage with bidirectional auxiliary switches. The inverter...
The Multilevel inverter is emerging as a new breed of power inverter option for high power applications, Especially for FACTS controllers. This can create high voltage and reduce harmonics by its own circuit topology. The power levels of the inverter are largely restricted by carrier frequency. For air cooled design the frequency is practically limited to 3 to 5 KHz for large inverters, hence to increase...
