Abstract:

Abstract Bit manipulation plays a significant role in high-speed digital signal processing (DSP) and data computing systems, and shift and rotation operations are crucial functions in it. In general, barrel shifters are used to perform these operations effectively. Nano magnetic logic circuits are among the promising beyond-CMOS alternative technologies for the design of high-speed circuits. Most of the existing circuits that have been developed using nano magnets are combinational circuits. In this work, a barrel shifter is implemented and realised using in-plane nano magnetic logic. The proposed design is the first of its kind nano magnetic logic circuit. The nano magnetic logic circuit implementation, layout generation, simulation, and validation were performed using the ToPoliNano and ModelSim tools. The logical equivalent design was synthesised and evaluated using the Synopsys Design Compiler tool. The proposed barrel shifter was realised using majority logic has 1769037 nano magnets with a boxing area of 481 × 13104 µm2 and 3276 clock zones after optimisation with the Barycenter algorithm. The proposed barrel shifter realised using Boolean logic has 315276 nano magnets with a boxing area of 265 × 5028 µm2 and 1257 clock zones after optimisation with the Barycenter algorithm. The proposed design results demonstrate that complex systems can be developed using nano magnetic logic by combining combinational and sequential circuits.

Abstract:

Magnetic skyrmion, a nano-sized spin texture with topological property, have the potential to develop high-density, low-power, and multifunctional spintronic devices. To realize the reconfiguration of a single logic device and the implementation of the complete logic functions, a new reconfigurable and reusable skyrmion logic is proposed and verified by micromagnetic simulation. Logic functions including AND, OR, NOT, NAND and NOR are realized in ferromagnetic (FM) nanotrack by skyrmion-edge repulsions and the voltage control of magnetic anisotropy (VCMA) effect. The working state of the potential well can be controlled by the link of the input signals, thus changing the function type. In addition, through reusing skyrmion in circular track, the energy required for creation and deletion is reduced. This work can provide guidance for the design and optimization of reconfigurable and reusable logic devices with circular track based on skyrmion.

Abstract:

Purpose Owing to recent challenges of CMOS manufacturing and power consumption in silicon technologies among alternative technologies, Nanomagnetic logic (NML) is one of the most promising technologies, so it was selected for this study. NML is non-volatile with ultra-low power dissipation that operates at room temperature. This paper aims to propose novel implementation of 2% and 4% multiplexers (MUXs) in NML technology. Design/methodology/approach The proposed multiplexers in NML technology are verified by HDL-based simulators. In addition, this study estimated area and power dissipation of the proposed design to compare and approve the promising improvements in comparison to other similar NML implementations. Findings The results show the remarkable improvements in terms of APDP term in comparison to the recent proposed MUXs in NML technology which are reported in Table 2. The proposed implementation of the MUX in NML is designed in three-dimensional layout to improve interconnection complexity which is an integration challenge. Also, by facilitating the routing signals and total wire length needed for clock signals, the negative impact of the power dissipated in clock wires is improved. Originality/value These findings would appeal to a broad audience, such as the readership of Microelectronics International Journal.

Abstract:

In this paper an ultra-compact all-optical encoder is presented by using a two-dimensional photonic crystal. The designed logic gate is based on the interference effect. The proposed structure consists of several photonic crystal waveguides connected by 2 nano-resonators. The nano-resonators are designed to reduce the size of the radius of the dielectric rods. The contrast ratios and delay time for the proposed all-optical encoder are respectively 6 dB and 125 fs. The size of the structure is equal to 132 µm2. Equality of the output power in the logic states “one”, the small dimensions, the low delay time, compact and simple structure have shown that the logic gate is suitable for the using in optical integrated circuits.

Abstract:

Nanotechnology has opened numerous ways for physically realizing very sophisticated nanodevices that can be fabricated exclusively using molecular engineering methods. However, the synthesis procedures that lead to the production of nanodevices are usually complicated and time consuming. For this reason, the destination materials should be well designed. Therefore, numerical simulations can be invaluable. In this work, we present numerical simulations of the magnetic behaviour of magnetic units shaped into nanometric strips as a low dimensional layout that can be used as nano-systems of combinatorial logic. We showed that magnetic layouts that contain fewer than 16 magnetic units can take on a specific configuration as a response to the input magnetic field. Such configuration can be treated as an output binary word. The layouts that contained various numbers of magnetic units showed different switching characteristics (utterly different order of inverting of strips’ magnetic moments), thus creating numerous combinations of the output binary words in response to the analog magnetic signal. The number of possible output binary words can be increased even more by adding parameters––the system’s initial magnetic configuration. The physical realization of the model presented here can be used as a very simple and yet effective encryption device that is based on nanometric arrays of magnetic units rather than an integrated circuit. The same information, provided by the proposed system, can be utilized for the construction of a nano-sensor for measuring of magnetic field with the possibility of checking also the history of magnetization.

Abstract:

Booming VLSI technology has graciously facilitated down-scaling dimensions of on-chip devices and interconnects in integrated circuits (ICs) to nano-miniaturized scale. However, at nano-dimensions where added benefits of scaling are constrained by associated highly-dense on-chip nano-interconnect structures, their electro-migration effects and several limiting signal-integrity issues. These cumulatively affect the quality of signal (QoS) at output. Improving output QoS is essential for attaining faithful system performance. The present paper judiciously attempts to address as well as limit this graving issue and is successfully proven by obtained results. Firstly, different structures and their performance of futuristic graphene based multi-layer graphene nano ribbon (MLGNR) interconnect is investigated. These include basic MLGNR and dielectric inserted side contact MLGNR (DS-MLGNR). Secondly, to improve data rates and performance, efficient and novel carbon nanotube field effect transistors (CNTFETs) based ternary logic system is incorporated for the prominent nano-MLGNR interconnects. Thirdly, QoS enhancement of highly potential DS-MLGNR interconnect is proposed using active shielding technique. Finally, is chase to further enrich QoS, adaptive least mean square (LMS) equalization technique is used at the receiver. The proposed work comprising of futuristic novel graphene interconnects with efficient ternary logic system together with adaption of several QoS improvement techniques are magnificent and panacea solution to limiting nano-interconnects in advanced ICs. Several interesting and seminal analyses such as delay, power, power-delay product, crosstalk, eye-diagram are performed that supports the novelty and effectiveness of the proposed work. The vivid performance analyses have been implemented at nano-size 10 nm technology node.

Abstract:

Novel two types of Carbon Nano Tube (CNT)-based multiplexers are introduced The first device is a solid-state transmission gate (t-gate) multiplexer that uses CNT as a channel in the Field Effect Transistors (FET) of both n-FET and p-FET types that are used. Because of its very small size, it has been shown that a CNT-based FET switches reliably using much less power than a silicon-based device, and thus the new device will consume less power than traditional t-gate multiplexer. The second new CNT device uses the fundamental Lorentz magnetic force from the basic laws of Electromagnetics as a switching mechanism between two conducting CNTs. The implementation of multiple-valued Galois logic using the new CNT devices is shown. Since a multiplexer is a fundamental logic block, the new devices can have a wide range of applications in a wide variety of nano circuits.

Abstract:

Magnetic skyrmions are promising potential information carriers for future spintronic devices owing to their nanoscale size, non-volatility and high mobility. In this work, we demonstrate the controlled manipulation of skyrmion motion and its implementation in a new concept of racetrack logical device by introducing an inhomogeneous perpendicular magnetic anisotropy (PMA) via micromagnetic simulation. Here, the inhomogeneous PMA can be introduced by a capping nano-island that serves as a tunable potential barriers/well which can effectively modulate the size and shape of isolated skyrmion. Using the inhomogeneous PMA in skyrmion-based racetrack enables the manipulation of skyrmion motion behaviors, for instance, blocking, trapping or allowing passing the injected skyrmion. In addition, the skyrmion trapping operation can be further exploited in developing special designed racetrack devices with logic AND and NOT, wherein a set of logic AND operations can be realized via skyrmion–skyrmion repulsion between two skyrmions. These results indicate an effective method for tailoring the skyrmion structures and motion behaviors by using inhomogeneous PMA, which further provide a new pathway to all-electric skyrmion-based memory and logic devices.

Abstract:

Conventional CMOS-based logic circuits are approaching their limits when it comes to speed and energy consumption, so the development of new electronic components becomes critical. Memristor is a nano-structured special electronic device with the advantages of simple structure, low power consumption and easy integration. This invention supplys a new method for developing complex logic circuits. This article mainly presents the design of a five-person voter circuit. The OR/AND logic can be accomplished by varying the polarity of two parallel memristors. On the basis of the two logic circuits, adder and comparator are constructed. Further, based on the adder and comparator, a five-person voter is implemented. The correctness and rationality of the five-person voter based on MRL are confirmed via logistical analysis and simulation. Compared with the traditional logic circuits, the logic circuit designed in this paper has advantages in area cost. The realization of the five-person voter circuit further proves that the logic circuit based on memristor can be cascaded. The research results are expected to build more complex circuits, which may provide a reference for the design of other practical circuits.

Abstract:

Graphene nano-crystalline carbon film/SiO2/p-Si heterostructures were fabricated with SiO2 interlayer thicknesses varying from 0 to 1000 nm, and their in-plane magnetoresistance (MR) was investigated. The results showed that, compared to the 0 nm SiO2 case, the presence of a 5 nm SiO2 interlayer significantly improved the room temperature MR by more than eight times (from 2.5% to 20.9% at 280 K). For SiO2 layers with thicknesses of 50 nm and above, only small negative MR values were observed. For all SiO2 thicknesses, the variations in the mobility of heterostructures were highly consistent with their MR performance. The results of this study provide a practical route to building graphene-based high-performance MR devices suitable for mass production as magnetic sensors and magnetic logic devices.

Abstract:

The base element of micromagnetic devices are the layered spin-valve structures. Small sizes, compatibility with the CMOS technology, scaling ability and various work conditions make the spin-valve structures a universal component of modern microelectronics. The purpose of present work is the analysis, systematization and generalization of the data of the work theoretical bases, experimental data and the application of spin valves. In the review, the hard disc drives, random-access magnetoresistive memory, the spin-transfer nano-oscillators, the magnetic biosensors, as well as various computing systems, operating on the principles of stochastic and deterministic logic, have been considered. The key theoretical works devoted to giant magnetoresistance and spin transfer have been used. The data on various types of the hard-disc readheads have been systematized, their architecture and parameters have been compared, and it has been shown how modern scientific research of nanomagnetic phenomena accelerates the growth rate of the recording density. The analysis of modern research devoted to magnetoresistive random access memory has been carried out. The problems of energy efficiency and increasing the degree of the integration for these devices have been discussed. The latest achievements in the field of materials, geometry and the properties of the spin-transfer nano-oscillators, as well as the problems and prospects for the development of this technology have been considered. The analysis of theoretical and experimental works, in which the spin-gate structures have been used to perform the logical operations of Boolean and non-Boolean logic, has been carried out. It has been shown how the probabilistic nature of the unstable switching of spin gates is used in the op-eration of the unconventional computing systems, namely, neuromorphic or Bayesian networks. The principles of operation of the spin valves as magnetic biosensors have been considered and the advantages of their application have been discussed.

Abstract:

With the application of DNA computing in more and more fields, the tasks are becoming more and more complex, and the scale of DNA circuits is gradually increasing. However, the current investigation of largescale circuits of DNA molecules is still a challenge. So it is crucial to optimize the performance of large-scale DNA circuits. In this paper, a large-scale digital logic circuit 16-Input-5-Output Priority Encoder is realized by using the DNA nano switches for the first time. The simulation of the 16-Input-5-Output Priority Encoder circuit shows that this method solves the problems of NOT gate instability and optimizes the DNA circuit in terms of reaction time, circuit complexity, and experimental difficulty. This paper proves the feasibility and superiority of using DNA nano switches to realize large-scale circuits, provides a new idea for realizing large-scale DNA circuits, and brings new development for the application of DNA circuits in biosensor, DNA complex computing and other fields.

Abstract:

Spin-orbit torque (SOT) can drive sustained spin wave (SW) auto-oscillations in a class of emerging microwave devices known as spin Hall nano-oscillators (SHNOs), which have highly nonlinear properties governing robust mutual synchronization at frequencies directly amenable to high-speed neuromorphic computing. However, all demonstrations have relied on localized SW modes interacting through dipolar coupling and/or direct exchange. As nanomagnonics requires propagating SWs for data transfer and additional computational functionality can be achieved using SW interference, SOT-driven propagating SWs would be highly advantageous. Here, we demonstrate how perpendicular magnetic anisotropy can raise the frequency of SOT-driven auto-oscillations in magnetic nanoconstrictions well above the SW gap, resulting in the efficient generation of field and current tunable propagating SWs. Our demonstration greatly extends the functionality and design freedom of SHNOs, enabling long-range SOT-driven SW propagation for nanomagnonics, SW logic, and neuromorphic computing, directly compatible with CMOS technology.

Abstract:

Spin torque oscillators (STOs) are emerging microwave devices that can potentially be used in spin-logic devices and the next-generation high-speed computing architecture. Thanks to their non-linear nature, STOs are easily tunable by the magnetic field and the dc current. Spin Hall nano-oscillators are promising types of STOs and most of the current studies focus on localized modes that can be easily excited. Here, we study using micromagnetic simulations, the nature of the spin-torque-induced excitations in nanowire devices made of perpendicular magnetic anisotropy (PMA) materials. Our results showed that, upon including PMA, the excitation of localized and propagating spin wave modes is feasible. We study the nature of the mode excitations as a function of the PMA strength ([Formula: see text]) and the current. Indeed, we estimate a critical value of [Formula: see text] to allow for the excitation of the propagating spin wave. We attribute this mode selectivity between localized and propagating modes to the magnitude and the change of the sign of the nonlinearity of the system from negative to positive at a non-zero [Formula: see text], which is supported by analytical calculations. Our results provide deep insight into engineering microwave devices for future magnonic and computational applications.

Abstract:

As the demands for improved performance of integrated circuit (IC) chips continue to increase, while technology scaling driven by Moore’s law is becoming extremely challenging, if not impractical or impossible, heterogeneous integration (HI) emerges as an attractive pathway to further enhance performance of Si-based complementary metal-oxide-semiconductor (CMOS) chips. The underlying basis for using HI technologies and structures is that IC performance goes well beyond classic logic functions; rather, functionalities and complexity of smart chips span across the full information chain, including signal sensing, conditioning, processing, storage, computing, communication, control, and actuation, which are required to facilitate comprehensive human–world interactions. Therefore, HI technologies can bring in more function diversifications to make system chips smarter within acceptable design constraints, including costs. Over the past two decades or so, a large number of HI technologies have been explored to increase heterogeneities in materials, technologies, devices, circuits, and system architectures, making it practically impossible to provide one single comprehensive review of everything in the field in one paper. This article chooses to offer a topical overview of selected HI structures that have been validated in CMOS platforms, including a stacked-via vertical magnetic-cored inductor structure in CMOSs, a metal wall structure in the back end of line (BEOL) of CMOSs to suppress global flying noises, an above-IC graphene nano-electromechanical system (NEMS) switch and nano-crossbar array electrostatic discharge (ESD) protection structure, and graphene ESD interconnects.

Abstract:

Scaling down the size of transistor in the nanoscale reduces the power supply voltage, as a result, the design of high-performance nano-circuit at low voltage has been considered. Most of digital circuits are composed of different components which determine the performance of the entire digital circuits. With the improvement of these components, the digital circuits can be optimized. One of these components is full adder for which various structures have been proposed to improve its performance, among them the two novel full adder structures are based on Gate-Diffusion Input (GDI) structure and half-classical XOR/XNOR logic (SEMI XOR/XNOR) modules. In this paper, Carbon Nanotube Field Effect Transistor (CNTFET)-based low power full adders by using SEMI XOR logic style and GDI structure are presented. Due to the incomparable thermal and mechanical properties of the CNTFET, it can be the first alternative to substitute the metal oxide field effect transistors (MOSFET). The digital circuits have the better performance based on CNTFET. Therefore, the three proposed full adders in this paper are designed based on CNTFET technology with many merits, such as low power dissipation, less energy delay product (EDP), and high speed at various supply voltages, frequencies, temperatures, load capacitors, and the number of tubes. Moreover, these proposed full adders occupy the minimum area consumption and have better performance in comparison with previous standard full adders. All simulations are done by using the Synopsys HSPICE simulator in 32 nm-CNTFET technology and layout of all full adder circuits are presented on Electric.

Abstract:

Abstract Self-heating effect (SHE) is a severe issue in advanced nano-scaled devices such as stacked nanosheet field-effect transistors (NS-FET), which raises the device temperature (T D), that ultimately affects the key electrical characteristics, i.e. threshold voltage (V T), DIBL, subthreshold slope (SS), I OFF, I ON, etc. SHE puts design constraints in the advanced CMOS logic devices and circuits. In this paper, we thoroughly investigated the impact of ambient temperature and interface thermal contact resistance induced-self heating effect in the NS-FET using extensive numerical simulations. The weak electron–phonon coupling, phonon scattering, and the ambient temperature-induced joule energy directly coupled with thermal contact resistance cause the SHE-induced thermal degradation, which increases the device temperature (T D) and affects the device reliability. The baseline NS-FET is well-calibrated with the experimental data and 3D quantum corrected drift-diffusion coupled hydrodynamic and thermodynamic transport models is used in our TCAD framework to estimate the impact of ambient temperature and interface thermal contact resistance on the device performance. Moreover, we also evaluate the SHE-induced performance comparison of NS-FET with conventional FinFET and found that thermal degradation in NS-FET potentially worsen the electrical characteristics. Thus, a detailed TCAD analysis shows that the ambient temperature and interface thermal contact resistances deteriorate the effective thermal resistance (R eff) and device performance metrics.

Spintronic device based on spin–orbit torque (SOT) is a potential candidate for the next-generation memory and logic devices. Here, we report a SOT-based programmable multi-state logic-in-memory in a single unit. Multi-step magnetization switching behaviors can be achieved in the device with a stacking structure based on Pt/Co bilayers and an Al2O3 spacer layer by varying the thickness of Co and Pt layers. Moreover, five logic gates (NOR, OR, AND, NAND, and NOT) have also been realized by controlling the current and magnetic field. This multi-state logic-in-memory opens a simple and effective way for designing single-unit spintronic devices and extends the potential application of the SOT-based devices in brain-like computations.

Abstract:

Magnetic skyrmions are topological quasiparticles with nanoscale size and high mobility, which have potential applications in information storage and spintronic devices. Here, we computationally investigate the dynamics of isolated skyrmions in a ferromagnetic racetrack, where magnetic properties of the edges are enhanced and modified, forming a channel with lower magnetic anisotropy for skyrmion motion. It is found that the rectangular notch at the edge can have a pinning effect on the skyrmion and enrich the dynamics of the skyrmion. Based on the racetrack with modified edges and the notch, we design a racetrack that realizes the skyrmionic logic AND, OR, and NOT gates as well as the diode in the same magnetic racetrack. It is found that the driving current density could be much smaller than those used in previous designs of skyrmion-based logic gates. By slightly altering the shape of the racetrack, we also design the NAND and NOR gates. Finally, we study the feasibility of our design at finite temperatures. Our results may contribute to the design of nonvolatile spintronic devices with integrated multiple functions and ultra-low energy consumption.

Abstract:

Abstract Logic gates have great importance in realization of rapid data transmission as well as low loss transfers. In this paper, a multi-objective inverse-design approach is implemented by using objective-first algorithm to design optical AND, OR, NAND and NOT logic gates on Si-platform at the design wavelength of 1.30 μm. For all gates, the design area is fixed to 2.24 μm × 2.24 μm. The optical logic ‘1’ output is accepted to be optical power values greater than 0.8 times of the input optical power. By implementing a Bias waveguide as well as two input ports, we made it possible to achieve logic ‘1’ output for logic operations having no inputs such as ‘0 NAND 0 = 1’ and ‘0 NOT = 1’. We binarized the proposed logic gates, and then numerically analyzed them by using finite-difference time-domain method. Proposed AND gate yields 1.20 times of input power for ‘1 AND 1 = 1’ logic operation and highest logic ‘0’ is obtained for logic operation of ‘1 AND 0 = 0’ as 0.40 times of the input power at the operating wavelength. It is also observed that proposed logic gates can operate not only at the design wavelength of 1.30 μm but also at broad wavelength regions as well. Finally, we demonstrate that it is possible to carry out complex logic operations by combining the proposed logic AND, OR and NAND gates to construct an XOR gate in the same platform.

Abstract:

There is a special class of logic gates, called universal gates, any one of which is sufficient to express any desired computation. The NAND gate is truly global, given that it is already known, each Boolean function can be represented in a circuit that contains only NOT and AND gates, it is sufficient to show that these gates can be defined from the NAND gate. The effect of Rashba spin-orbit interaction (SOI) on the gate response and spin current density in a series of non-interacting one-dimensional rings connected to some leads is studied theoretically within the waveguide theory. The gates response and spin current density are computed in geometry of the system containing two terminal double quantum rings. Also, the presence and absence of Rashba SOI are treated as the two inputs of the AND/NAND/NOT gates. Furthermore, simulation of the device performance demonstrates that vital improvement toward spintronic applications can be achieved by optimizing device parameters such as magnetic flux and Rashba coefficient.

Abstract:

Today’s technology demands compact, portable, fast, and energy-efficient devices. One approach to making energy-efficient devices is an in-memory computation that addresses the memory bottleneck issues of the present computing system by utilizing a spintronic device viz. magnetic tunnel junction (MTJ). Further, area and energy can be reduced through approximate computation. We present a circuit design based on the logic-in-memory computing paradigm on voltage-controlled magnetic anisotropy magnetoresistive random access memory (VCMA-MRAM). During the computation, multiple bit cells within the memory array are selected that are in parallel by activating multiple word lines. The designed circuit performs all logic operations-Read/NOT, AND/NAND, OR/NOR, and arithmetic SUM operation (1-bit approximate adder with 75% accuracy for SUM and accurate carry out) by slight modification using control signals. All the simulations have been performed at a 45 nm CMOS technology node with VCMA-MTJ compact model by using the HSPICE simulator. Simulation results show that the proposed circuit’s approximate adder consumes about 300% less energy and 2.3 times faster than its counterpart exact adder.
