Dependence of RF/Analog and Linearity Figure of Merits on Temperature in Ferroelectric FinFET: A Simulation Study

Abstract: This article presents a simulation study of the impact of variation in temperature on the transfer characteristics and the RF/analog performance like transconductance ( ${g}_{m}$ ), gate capacitance ( ${C}_{gg}$ ), cutoff frequency ( ${f}_{t}$ ), and transconductance frequency product (TFP) of the ferroelectric FinFET (Fe-FinFET). In addition, the impact of temperature on the linearity parameters such as higher order harmonics ( ${g}_{m2}$ and ${g}_{m3}$ ), second- and third-order voltage intercept points (VIP2 and VIP3), third-order power-intercept point (IIP3), third-order intermodulation distortion (IMD3), and 1-dB compression point is estimated for wide variation of temperature in the Fe-FinFET. It is seen that temperature has a significant impact on the RF/analog and linearity parameters, and these figure of merits (FoMs) are the functions of temperature. Analysis reports that RF/analog parameters are suppressed, whereas the linearity FoMs are improved as temperature changed from 250 to 350 K.

Sustainable Use of GGBS and RHA as a Partial Replacement of Cement in the Stabilization of Indian Peat

Abstract: The cement stabilization of peat has been prevalent traditionally throughout the years across the world. However, the drawbacks associated with the manufacturing process of cement finally lead to a great climatic change and environmental threats. Therefore, considering this issue, the present study encourages the use of industrial waste, ground granulated blast furnace slag (GGBS) and agricultural waste, rice husk ash (RHA) as a partial replacement of cement in the stabilization of Indian peat. The collected peats varies with four diverse ranges of organic content (20–76%) comprising three different states in the northeastern province of India. The collected peats were stabilized using cement (5–30%) followed by the determination of optimum cement content based on strength and acidity criteria. The replacement of the cement with GGBS and RHA was done in three different percentages (i.e., 30%, 50%, and 70%) at their optimum cement content. The experimental investigations include compaction, unconfined compressive strength (UCS), pH, electric conductivity (EC), field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). The influence of the various proportions of cement–GGBS and cement–RHA mixture, organic content and curing days were addressed precisely. The UCS results reveal that the replacement of cement with GGBS and RHA brings a relatively less strength development as compared to cement alone. However, this study suggests a maximum of 30% cement replacement from their optimum cement content for low organic peat ( 66%) is seen to be more. The pH and EC decreases after the replacement of cement which reduces the ion (Ca2+ and OH−) generation in pore fluid system. FESEM and XRD analyses confirm that the reaction products responsible for strength gain are the same as obtained in cement stabilization. Finally, the replacement of cement with GGBS gives relatively better performance than that of RHA. As GGBS and RHA are an environs threat, thus use of such waste materials can be a well sustainable solution for treating organic soil and peat.

Blockchain: A Tale of Peer to Peer Security

Abstract: The underlying or core technology of Bitcoin cryptocurrency has become a blessing for human being in this era. Everything is gradually changing to digitization in this today’s epoch. Bitcoin creates virtual money using Blockchain that’s become popular over the world. Blockchain is a shared public ledger, and it includes all transactions which are confirmed. It is almost impossible to crack the hidden information in the blocks of the Blockchain. However, there are certain security and technical challenges like scalability, privacy leakage, selfish mining, etc. which hampers the wide application of Blockchain. In this paper, we briefly discuss this emerging technology namely Blockchain. In addition, we extrapolate in-depth insight on Blockchain technology.
