Neural networks, having the computational power and learning ability similar to the brain is one of the key AI technologies. Neuromorphic computing system (NCS) consists of the synaptic device, neuronal circuit, and neuromorphic architecture. Memristor are a promising candidate for neuromorphic computing systems, but when it comes to neuromorphic computing, the conductance behavior of the synaptic memristor or neuronal memristor needs to be studied thoroughly in order to fathom the neuroscience or computer science. Furthermore, there is a need of more simulation work for utilizing the existing device properties and providing guidance to the development of future devices for different performance requirements. Hence, development of NCS needs more simulation work to make use of existing device properties. This work aims to provide an insight to build neuronal circuits using memristors to achieve a Memristor based NCS.  Here we throw a light on the research conducted in the field of memristors for building analog and digital circuits in order to motivate the research in the field of NCS by building memristor based neural circuits for advanced AI applications. This literature is a step in the direction where we describe the various Key findings about memristors and its analog and digital circuits implemented over the years which can be further utilized in implementing the neuronal circuits in the NCS. This work aims to help the electronic circuit designers to understand how the research progressed in memristors and how these findings can be used in implementing the neuronal circuits meant for the recent progress in the NCS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analog%20circuits" title="analog circuits">analog circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20circuits" title=" digital circuits"> digital circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=memristors" title=" memristors"> memristors</a>, <a href="https://publications.waset.org/abstracts/search?q=neuromorphic%20computing%20systems" title=" neuromorphic computing systems"> neuromorphic computing systems</a> </p> <a href="https://publications.waset.org/abstracts/100057/memristor-a-promising-candidate-for-neural-circuits-in-neuromorphic-computing-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100057.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3061</span> One Period Loops of Memristive Circuits with Mixed-Mode Oscillations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wieslaw%20Marszalek">Wieslaw Marszalek</a>, <a href="https://publications.waset.org/abstracts/search?q=Zdzislaw%20Trzaska"> Zdzislaw Trzaska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interesting properties of various one-period loops of singularly perturbed memristive circuits with mixed-mode oscillations (MMOs) are analyzed in this paper.

This claim is nowadays pushing toward a new circuit design paradigm in which the traditional analog signal processing is expected to be progressively substituted by the processing of times in the digital domain. Within this novel paradigm, digitally controlled delay lines (DCDL) should play the role of digital-to-analog converters in traditional, analog-intensive, circuits. Digital delay locked loops are highly prevalent in integrated systems.The proposed paper addresses the glitches present in delay circuits along with area,power dissipation and signal integrity.The digitally controlled delay lines(DCDL) under study have been designed in a 90 nm CMOS technology 6 layer metal Copper Strained SiGe Low K Dielectric. Simulation and synthesis results show that the novel circuits exhibit no glitches for dual output coarse DCDL with less power dissipation and consumes less area compared to the glitch free NAND based DCDL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glitch%20free" title="glitch free">glitch free</a>, <a href="https://publications.waset.org/abstracts/search?q=NAND-based%20DCDL" title=" NAND-based DCDL"> NAND-based DCDL</a>, <a href="https://publications.waset.org/abstracts/search?q=CMOS" title=" CMOS"> CMOS</a>, <a href="https://publications.waset.org/abstracts/search?q=deep-submicrometer" title=" deep-submicrometer"> deep-submicrometer</a> </p> <a href="https://publications.waset.org/abstracts/2876/low-power-glitch-free-dual-output-coarse-digitally-controlled-delay-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2876.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3059</span> Multiple Fault Diagnosis in Digital Circuits using Critical Path Tracing and Enhanced Deduction Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Mahmoud">Mohamed Mahmoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper has developed an effect-cause analysis technique for fault diagnosis in digital circuits.

The technique obtains closed form expressions for the equivalent circuits which are used to model these discontinuities. Then, it would be easy to handle and to characterize complicated structures like T and Y junctions, truncated junctions, arbitrarily shaped junctions, cascading junctions and more generally planar multiport junctions. Another advantage of this method is that the edge line concept for arbitrary shape junctions operates with real parameters circuits. The validity of the method was further confirmed by comparing our results for various discontinuities (bend, filters) with those from HFSS as well as from other published sources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD%20analysis" title=" CAD analysis"> CAD analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20circuits" title=" microwave circuits"> microwave circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=S-parameters" title=" S-parameters"> S-parameters</a> </p> <a href="https://publications.waset.org/abstracts/25946/characteization-and-optimization-of-s-parameters-of-microwave-circuits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3045</span> Optimizing Power in Sequential Circuits by Reducing Leakage Current Using Enhanced Multi Threshold CMOS </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patikineti%20Sreenivasulu">Patikineti Sreenivasulu</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20srinivasa%20Rao"> K. srinivasa Rao</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Vinaya%20Babu"> A.

The increase in power consumption, coupled with the increasing demand for portable/hand-held electronics, has made power consumption a dominant concern in the design of VLSI circuits today. MTCMOS technology provides low leakage and high performance operation by utilizing high speed, low Vt (LVT) transistors for logic cells and low leakage, high Vt (HVT) devices as sleep transistors. Sleep transistors disconnect logic cells from the supply and/or ground to reduce the leakage in the sleep mode. In this technology, energy consumption while doing the mode transition and minimum time required to turn ON the circuit upon receiving the wake up signal are issues to be considered because these can adversely impact the performance of VLSI circuit.

By the traces of coefficients of the fractional-delay FIR filter, it is found that the conventional method of polynomial substitution for filter coefficients no longer satisfies the design demand, and the circuits perform the sinc function (sinc converter) are added to overcome this problem.

The results of PSPICE simulation program are corresponding to the theoretical analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=current-mode" title="current-mode">current-mode</a>, <a href="https://publications.waset.org/abstracts/search?q=quadrature%20oscillator" title=" quadrature oscillator"> quadrature oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=block%20diagram" title=" block diagram"> block diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=CDTA" title=" CDTA"> CDTA</a> </p> <a href="https://publications.waset.org/abstracts/8914/first-order-filter-based-current-mode-sinusoidal-oscillators-using-current-differencing-transconductance-amplifiers-cdtas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8914.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">453</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3041</span> Importance of Hardware Systems and Circuits in Secure Software Development Life Cycle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mir%20Shahriar%20Emami">Mir Shahriar Emami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although it is fully impossible to ensure that a software system is quite secure, developing an acceptable secure software system in a convenient platform is not unreachable.

As a result, the degradation of high-speed digital circuits due to signal integrity issues such as coupling effects, clock feedthrough, crosstalk noise and delay uncertainty noise. Crosstalk noise in VLSI interconnects is a major concern and reduction in VLSI interconnect has become more important for high-speed digital circuits. It is the most effectively considered in Deep Sub Micron (DSM) and Ultra Deep Sub Micron (UDSM) technology. Increasing spacing in-between aggressor and victim line is one of the technique to reduce the crosstalk. Guard trace or shield insertion in-between aggressor and victim is also one of the prominent options for the minimization of crosstalk. In this paper, far end crosstalk noise is estimated with mutual inductance and capacitance RLC interconnect model. Also investigated the extent of crosstalk in capacitive and inductively coupled interconnects to minimizes the same through shield insertion technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VLSI" title="VLSI">VLSI</a>, <a href="https://publications.waset.org/abstracts/search?q=interconnects" title=" interconnects"> interconnects</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20integrity" title=" signal integrity"> signal integrity</a>, <a href="https://publications.waset.org/abstracts/search?q=crosstalk" title=" crosstalk"> crosstalk</a>, <a href="https://publications.waset.org/abstracts/search?q=shield%20insertion" title=" shield insertion"> shield insertion</a>, <a href="https://publications.waset.org/abstracts/search?q=guard%20trace" title=" guard trace"> guard trace</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20sub%20micron" title=" deep sub micron"> deep sub micron</a> </p> <a href="https://publications.waset.org/abstracts/87200/signal-integrity-performance-analysis-in-capacitive-and-inductively-coupled-very-large-scale-integration-interconnect-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87200.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">185</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3039</span> Digital Preservation: Requirement of 21st Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Kumar">Gaurav Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shilpa"> Shilpa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital libraries have been established all over the world to create, maintain and to preserve the digital materials.

Reinterpreting the diachroneity of 'intertextuality' in the context of misreading theory extended the range of the 'intermediality' of transmedia to the intense tension between digital images and symbolic images throughout history of images. With the analogy between six categories of revisionary ratios and six steps of digital transformation, digital rhetoric might be illustrated as a linear process reflecting dynamic, intensive relations between digital moving images and original static images. Finally, it was concluded that two-way framework of the rhetoric of transformation of digital images and reversed served as a renarrative structure to revive static images by reconnecting them with digital moving images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhetoric" title="rhetoric">rhetoric</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20art" title=" digital art"> digital art</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediality" title=" intermediality"> intermediality</a>, <a href="https://publications.waset.org/abstracts/search?q=misreading%20theory" title=" misreading theory"> misreading theory</a> </p> <a href="https://publications.waset.org/abstracts/100230/rhetoric-and-renarrative-structure-of-digital-images-in-trans-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100230.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3036</span> Jordan Curves in the Digital Plane with Respect to the Connectednesses given by Certain Adjacency Graphs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Josef%20Slapal">Josef Slapal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digital images are approximations of real ones and, therefore, to be able to study them, we need the digital plane Z2 to be equipped with a convenient structure that behaves analogously to the Euclidean topology on the real plane. In particular, it is required that such a structure allows for a digital analogue of the Jordan curve theorem. We introduce certain adjacency graphs on the digital plane and prove digital Jordan curves for them thus showing that the graphs provide convenient structures on Z2 for the study and processing of digital images. Further convenient structures including the wellknown Khalimsky and Marcus-Wyse adjacency graphs may be obtained as quotients of the graphs introduced. Since digital Jordan curves represent borders of objects in digital images, the adjacency graphs discussed may be used as background structures on the digital plane for solving the problems of digital image processing that are closely related to borders like border detection, contour filling, pattern recognition, thinning, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20plane" title="digital plane">digital plane</a>, <a href="https://publications.waset.org/abstracts/search?q=adjacency%20graph" title=" adjacency graph"> adjacency graph</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan%20curve" title=" Jordan curve"> Jordan curve</a>, <a href="https://publications.waset.org/abstracts/search?q=quotient%20adjacency" title=" quotient adjacency"> quotient adjacency</a> </p> <a href="https://publications.waset.org/abstracts/65454/jordan-curves-in-the-digital-plane-with-respect-to-the-connectednesses-given-by-certain-adjacency-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">379</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3035</span> Digital Leadership and HR practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Konstantinou">Joanna Konstantinou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the pandemic, we have recently witnessed an explosion of HR Tech offering a variety of solutions for digital transformation, as well as a large number of HR practices implemented by professionals both in data science and occupational psychology.

Then it would be easy to handle and to characterize complicated structures like T and Y junctions, truncated junctions, arbitrarily shaped junctions, cascading junctions, and more generally planar multiport junctions. Another advantage of this method is that the edge line concept for arbitrary shape junctions operates with real parameters circuits.
