This paper presents a Cylindrical GAA TFET based on germanium source for low power applications. The proposed device used the merits of low band gap material such as germanium, which is used as a material in the source region. Device investigations have been made in terms of DC characteristics like ION, IOFF, SS, ION/IOFF. The proposed device increases ON-current as high as 1.9 × 10−5 A/μm, which...
In this paper, analytical and simulation based analysis to verify the inherent properties of SiGe HBT is done. The major performance parameters of SiGe HBT are cut-off freuency fT, maximum oscillation frequency fmax, base transit time τb, current gain β and electron mobility μn of SiGe base. These performance parameters are responsible for the reliability of SiGe HBT. Temperature is one of the major...
RSSI method is used to measure the distance between beacon nodes and unknown node. This technique is not more relevant because the radio frequency (RF) signals are mostly affected with the noise available in the environment. Therefore, the accurate distance evaluation cannot possible between the known nodes and unknown nodes. RSSI method is having many accuracy challenges which need improvements....
This paper describes a comparative study of sensitivity and non-linearity of conventional and bossed diaphragm piezoresistive pressure sensor along with a performance enhanced design. The proposed structures take into consideration corner compensation to avoid distortion of the mesa structure during fabrication of bossed diaphragm structure using wet bulk micromachining. Optimum piezoresistors locations...
Pressure microsensors are very frequently used for applications encompassing a wide range of operating pressure ranges. However, it is possible to use the same pressure sensor for different operating ranges (in a limited range) with satisfactory performance. In this work, we report the possibility of using a single sensor for different pressure ranges. Operating the sensor at a lower pressure range...
A compact analytical model is presented for crossover point, subthreshold slope, virtual cathode position, and threshold voltage for a short-channel quadruple-gate (QuaG) gate-all-around (GAA) MOSFET. The potential distribution in the channel is obtained by an analytical solution of 3-D Poisson’s equation, where the electron quasi-Fermi level is approximated to be zero for low drain-to-source voltages...
Efficient segmentation of noisy Magnetic Resonance ( MR) brain images is a challenging task, as pre and post surgery decisions are required to make accurately in achieving better medical practices while treating brain disorders. This paper presents an automatic segmentation technique to remove non brain tissue (skull, fat, skin, muscle) of noisy MR brain images and to extract brain tissue (cortex...
With the efforts being done to make the existing power network smarter and efficient, thermal monitoring of transformers has become the demand of the day in the field of transformer engineering. Theoretical methods available and practical measurement techniques will not suffice, hence the development of thermal modeling techniques that can measure the thermal profile across the transformer at desired...
