A lifting domain reversible data hiding is presented here. A content based watermark is produced from selective $(4times 4)$ sized coefficient blocks of particular sub-band. One covert key is utilized to secure the watermark for access management which is specified by user. The secure watermark is implanted within same coefficient block $(4times 4)$. In receiver side the retrieval of original image is done by the authentic user's secure key. For real time application the ‘very large scale integration’ (VLSI) architecture of this proposed encoder is designed in hardware. Simulation of the encoder is done by ‘field programmable gate array’ (FPGA) kit. The experimentation is performed over a range of benchmark images. The results justify the supremacy of the method. The encoder module consumes only 59.20mW power when operated at 120.135MHz frequency in case of real time implementation.
提出了一种提升域可逆数据隐藏方法。基于内容的水印是由特定子带的选择性$(4 × 4)$大小的系数块产生的。利用一个隐蔽密钥对用户指定的水印进行访问管理。安全水印被植入同一系数块$(4 × 4)$中。在接收端,原始图像的检索由真实用户的安全密钥完成。为了实时应用,该编码器的“超大规模集成”(VLSI)架构在硬件上进行了设计。编码器的仿真由“现场可编程门阵列”(FPGA)套件完成。实验是在一系列基准图像上进行的。结果证明了该方法的优越性。在实时实现的情况下,编码器模块工作在120.135MHz频率下,功耗仅为59.20mW。

The FinFET transistor is now considered the most probable successor of the bulk MOSFET transistor in the global race for miniaturization in the field of micro- and nanoelectronics. The development of integrated circuits using FinFETs is made possible only by the use of their compact models. These models must predict precisely the electrical behavior of these devices advanced technologies. In this work, we show an integrated approach for SPICE parameter extraction explicitly for nanoscale FinFETs, which is validated by comparisons with simulation results. We discuss in detail the platform necessary for the development of the model and automated SPICE parameter extraction. The predictive capability of TCAD to estimate the SPICE model parameters from process-based on the physical variations of process parameters has been examined.

Bandgap width within first Brillouin zone in metamaterial-based two-dimensional photonic crystal structure is analytically computed using plane wave expansion method. A wider range of negative refractive index is considered for simulation purpose within physically feasible limit whereas rectangular geometrical shape is taken into account for the analysis with TE mode of propagation. Artificial materials in presence of air holes are considered to achieve negative index, and results are compared with that obtained for conventional SiO2-air material system with equivalent dimensional configuration. Coordinates of two peak points, $hbox{`}Gammahbox{'}$ point and ‘X’, point are noted for all the DNG materials which give the indication of blueshift of the valence region with change of negative refractive index. Simulated findings speak in favor of multiple forbidden regions for some specific material systems which can be utilized to design photonic multi-channel filter in beyond THz region.

With time the design of RF and Analog application based circuits in MOSFET industry is changing and day by day it's becoming more and more difficult as device modeling has now entered the deep-subnanometer regime. Performance of junction less transistor is remarkable in digital application due to their ease of fabrication and superior SCEs. This paper highlights the DC, ANALOG, RF and LINEARITY performance of a Junction less Double Gate MOSFET (JL DG MOSFET) by downscaling the Channel length with the help of numerical TCAD device simulator (SILVACO). The figure of merits for DC, ANALOG, RF & LINEARITY parameters for example Transconductance $(mathrm{g}_{mathrm{m}})$, Gain transconductance frequency product (GTFP), output resistance $(mathrm{R}_{mathrm{o}mathrm{u}mathrm{t}})$, cut-off frequency $(mathrm{f}_{mathrm{T}})$, Gain bandwidth product (GBW), Transconductance generation factor $(mathrm{g}_{mathrm{m}}/mathrm{I}_{mathrm{d}})$, maximum frequency $(mathrm{f}_{max})$, Intermodulation distortion (IMD), variable intercept point (VIP) are studied and impact of downscaling in gate length have been recorded. The results conclude that down scaled junction less DG MOSFET show a great pledge to turn out to be a feasible competitor for use in SOC application.
随着时间的推移,MOSFET工业中基于射频和模拟应用的电路设计也在不断变化,随着器件建模进入深亚纳米阶段,设计难度也越来越大。无结晶体管由于其易于制造和优越的晶圆结构而在数字应用中表现突出。本文在数值TCAD器件模拟器(SILVACO)的帮助下,通过减小通道长度,重点介绍了无结双栅极MOSFET (JL - DG MOSFET)的直流、模拟、射频和线性性能。直流、模拟、射频和线性参数的优点图,例如跨导$( mathm {g}} { mathm {m}})$、增益跨导频率积(GTFP) $、输出电阻$( mathm {R}} { mathm {o} mathm {u} mathm {t}})$、截止频率$( mathm {f}} { mathm {t}})$、增益带宽积(GBW)、跨导产生因子$( mathm {g}} { mathm {m}}/ mathm {I}} { mathm {d}} $、最大频率$( mathm {f}} {max})$、互调失真(IMD)、对可变截距点(VIP)进行了研究,记录了栅极长度降尺度的影响。结果表明,小尺寸无结DG MOSFET在SOC应用中显示出巨大的潜力。

The introduction of Field Effect Transistor (FinFET) Technology played a leading contender in today microelectronics. FinFET structure allows to scale the device at sub-nanometer. Short channel effects can be suppressed by formation of ultra-thin fin in FinFET device. In this paper we compared the performance of the 20nm FinFET device by using different dielectric materials. We have considered only n-channel FinFET device. Simulation carried on the electron mobility, potential distribution, energy band of hole and electron, on-off current ratio (Ion/Ioff) and power dissipation of device with respect to the applied gate voltage. Mobility enhancement and higher current ratio (Ion/Ioff) is observed in proposed FinFET device having high k-dielectric material at lower voltage. This designed can be useful for low power applications due to low power dissipation. In high k-dielectric material, 1.41% improvement is observed in potential voltage with respect to low k- dielectric material when $mathbf{V}_{mathbf{gs}}$ at low voltage and 0.98% improvement is observed when $mathbf{V}_{mathbf{gs}}$ at high voltage. In high k- dielectric material 15% hike is observed in the energy conduction band as compared to low k-dielectric material when $mathbf{V}_{mathbf{gs}}$ at low voltage and 14% hike is observed when $mathbf{v}_{mathbf{gs}}$ at high voltage.
场效应晶体管(FinFET)技术的引入在当今微电子领域发挥了领先的竞争优势。FinFET结构允许器件在亚纳米级进行缩放。在FinFET器件中,超薄翅片的形成可以抑制短通道效应。本文比较了采用不同介质材料制备的20nm FinFET器件的性能。我们只考虑了n通道FinFET器件。对器件的电子迁移率、电势分布、空穴和电子能带、通断电流比(Ion/Ioff)和功耗随外加栅极电压的变化进行了仿真。在较低电压下,采用高k介电材料的FinFET器件可提高迁移率和电流比(Ion/Ioff)。由于功耗低,该设计可用于低功耗应用。在高k介电材料中,当$mathbf{V}_{mathbf{gs}}$处于低k介电材料时,电位电压提高了1.41%;当$mathbf{V}_{mathbf{gs}}$处于高压时,电位电压提高了0.98%。在高k介电材料中,与低k介电材料相比,$mathbf{V}_{mathbf{gs}}$在低电压下的导能带增加了15%,$mathbf{V}_{mathbf{gs}}$在高电压下的导能带增加了14%。

The analytical surface potential model of 22nm salient source Double Gate TFET (SS-DG-TFET) is presented in this paper. The surface potential is analyzed as the performance parameter along with an assessment of improved ON/ OFF current ratio. The variation of tunnel current is examined under same front and back gate bias together with identical oxide thickness. The source region has been extended symmetrically in both directions in order to enhance the conductivity of the channel region and it has been efficiently deployed in the proposed model. The execution of low power functionality and lower sub-threshold slope is also established in this model. The analytical results have been suitably validated using Silvaco, Atlas.

This paper evaluates the performance of three operational amplifier (Op-Amp) based instrumentation amplifier (INA) topology using two variants of Op-Amp - one with a very high gain with respect to the other Op-Amp topology. The gain accuracy and common mode rejection ratio (CMRR) of the INA is improved with the use of the very high gain Op-Amp designed using a folded cascode amplifier. The CMRR of the INA using folded cascade Op-Amp is 114 dB which is 43 dB higher to that of INA using differential amplifier.

Along with the cost curves or cost coefficients valve point effect has also very important impact in ELD. So in this paper, for ELD with valve point effect has been optimized with the help of Adaptive Jaya Optimization Technique. 13 thermal unit has been taken to get the optimal power output and optimal cost, which has been compared to the other optimization techniques' results. Advantage of this proposed optimization technique has been shown in the current work.","PeriodicalId":294095,"journal":{"name":"2019 Devices for Integrated Circuit (DevIC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121180130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
