Here, the catalytic metal gate approach is used to develop the computational model of the gas sensor. Moreover, the performance metrics of this MOSFET based phosphine gas sensor is estimated by examining the comparative variation in the on-state current and threshold voltage in respect of metal (gate) work function modulation with the gas exposure. Sensitivity profile shows that the proposed device is capable of having 24% higher Vth sensitivity than silicon based DGS-MOSFET. Additionally, the device sensitivity is optimized by considering various channel materials such as SiGe, Si, and IGZO. In comparison with SiGe, Si and IGZO, InGaN-based DGS-MOSFET is capable of providing better Vth sensitivity for PH3 detection. Furthermore, the high-k gate oxide material is also optimized based on the sensitivity profile of the device.","PeriodicalId":307414,"journal":{"name":"2022 IEEE VLSI Device Circuit and System (VLSI DCS)","volume":"11966 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133788342","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}

Similarly, the effect of noise on conventional TFET and LTFET has been investigated at 1 MHz and 1 GHz and high frequency (HF) to check the viability of proposed devices. In LTFET device structures, the gate-source overlapping accelerates the electric field, improves the tunneling rate and increases the drain current. The gate-source overlapping region used in LTFET enhances the tunneling area that further enhance the drain current. The proposed LTFET device shows good performance in terms of ION-IOFF ratio and is well suited for applications operating at low power.","PeriodicalId":307414,"journal":{"name":"2022 IEEE VLSI Device Circuit and System (VLSI DCS)","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131984214","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}

Beam spot sizes for individual cases are obtained referencing input power at 0 dBm. Simulation is carried out for fundamental mode along with two other modes; and therefore, power in each carrier may equivalently be considered as large for single channel system. Both input and output OSNR are also computed at this operating spectrum using Optiwave software.

P2P is inherently possible in the PCIe domain because of the Address based and ID based routing characteristics of the single root PCIe topology. CMB (controller memory buffer) can be utilized in PCIe based NVMe (Non-Volatile Memory Express) SSDs to achieve P2P transfer without involving the Host CPU & DRAM [1]. Now a days Data Centers trending to migrate to a scalable, disaggregated storage transports like NVMeoF (Non-Volatile Memory Express Over Fabrics) [4]. Moreover, peers may reside on different racks of Data Center connected with NVMeoF transport. Currently there is no inherent method available to use CMB feature [5] and doing P2P transfer in NVMeoF. In this paper we approach this problem by using VUC (vendor unique command) for sharing Peer's connection information & establishing a dedicated P2P QP (Queue pair) connection among the peer Ethernet SSDs. Through this method the host CPU will just give control messages to initiate the P2P transfer so that highly intensive IO transfer responsibility is fully offloaded to peer NVMeoF SSDs. The proposed approach is energy efficient and nullifies the power consumed by Host DRAM for data copy & reduces load on ethernet switch to half, while the data copy speed is doubled without affecting the throughput.","PeriodicalId":307414,"journal":{"name":"2022 IEEE VLSI Device Circuit and System (VLSI DCS)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116705969","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}

In this connection, LQR control theory helps to obtain the feedback gain optimally using quadratic cost function. The weight adjustment matrices in LQR control theory requires to adjust in order to achieve desired system response.

Because sensor nodes (SN) remain unattended after deployment, their energy (battery supply) and computational capabilities restrict the network's lifespan. The sources of energy must be effectively utilized in order to keep the networks running for a long time. As a result, the WSN's two most important criteria are optimal node location estimate and efficient energy consumption. The Spider Cat Swarm Optimization (SCSO) method is used in this study to optimize the network layout by including it into the load - balancing. The efficiency of the SCSO algorithm-based clustering method is examined in simulation and confirmed in a present experimental. By simulated results, the performance of other treatments based on traditional Modified Low-energy Adaptive Clustering Hierarchy (MODLEACH) and evolutionary method Optimized Swarm Optimization (OPSO) is also investigated and assessed.

Human behavioral and physiological components have the biggest alternative to overcome these security issues. In any case, the current biometric authentication methodology like fingerprints, faces and iris are profoundly complex methods. So in this paper, a new authentication system i.e. Finger vein authentication with the help of Deep Convoluted Siamese network has been proposed. The region of interest was done by threshold value over captured images by NIR and CCD cameras. After that, the Deep convoluted Siamese network is used to compare and contrast between two images to predict whether the two images are similar or not. The modern Siamese network uses a \"Triplet Loss Function\". In this triplet loss function, three fundamental images (Anchor Image, Positive Image and Negative Image) are considered where each image is a pixel matrix. The detection accuracy for testing and training is 97.2% and 96.4 % which is compared by utilizing several machine learning techniques (ANFIS, SVM, MLP and Global mapping/SVM) accuracy. It is clear from the comparative analysis that the proposed method gives better results than other algorithms. The proposed methodology TPR, FPR, FNR and TNR are 0.916, 0.027, 0.041 and 0.027 respectively. From these values, it is obvious that the proposed model gives better results, as the TP value is higher while the FP, FN and TN value are lower.","PeriodicalId":307414,"journal":{"name":"2022 IEEE VLSI Device Circuit and System (VLSI DCS)","volume":"267 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121483799","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}
