Comparators are a critical element of Analog-to-Digital converters (ADCs) intended to operate in a harsh environments such as the automotive. The influence of temperature on key comparator properties such as the delay must be well understood to maximize their speed. In this paper a Double-Tail latch analysis leads to an analytical expression for the delay to more accurately guide the design over a...
The availability and reasonable cost of broadband Internet made it an attractive and favourable option to billions of users worldwide. Being a fast service also encourages its users to use real-time applications which is streaming and live data transfer includes VoIP and video streaming. The performance of such applications in Wireless Local Area Network (WLAN) may be highly affected by security protocols...

Although, it was shown that NC is a promising technique to improve the throughput; especially for multicast environment; it also bears negative side-effects (e.g., high decoding delay). Since streaming video are usually subject to strict delay constraints, high decoding delay must be resolved to enhance the performance of the NC schemes. To overcome this issue, this paper presents a new scheme named...
This paper proposes a brain signals based method to evaluate a human operator workload while teleoperating a mobile robot in presence of time delay. The procedure based on denoising and decomposition wavelet transform can be applied to raw EEG signals, analyzing the energy in the delta band to detect four states of cognitive workload. The index obtained is validated using the NASA-TLX question nary...
Content-addressable memory (CAM) is the hardware based particular type of memory device utilized for low power and high-speed application. CAMs are developed for precise application without sacrificing their search speed, and it is much faster than random accessmemory (RAM) in search application. CAM executes two essential functions storing and comparing. The additional circuitry during comparison...
Ethernet based secure VPLS (Virtual Private LAN Services) networks require to establish full mesh of VPLS tunnels between the customer sites. However, the tunnel establishment between geographically distant customer sites introduces a significantly high delay to the user traffic transportation.In this article, we propose a novel fast transmission mechanism for secure VPLS architectures to reduce the...
In recent years, Hardware-In-the-Loop (HIL) simulation such as RT-LAB, RTDS are widely used in power electronic system study. In order to keep the simulation accuracy, the main concern of researchers normally focuses on the minimum simulation step size of the simulator, while neglects the role of input-to-output delay of the simulator. Concentrating on the study of hysteresis current control of grid...
Currently and due to its wide use, the wireless networks in conformance with IEEE 802.11 standard are generating channels saturation, that provokes interference between themselves. IEEE 802.11n is one of the standards that offers greater benefits to improve the wireless network performance. In this paper we analyze the performance of wireless network in conformance with IEEE 802.11n standard to evaluate...
In this article, we analyze the performance evaluation of WiFi technology in conformance with IEEE 802.11b/n/ac standards and Wireless Distribution System (WDS) for indoor environments with and without obstacles. We present different scenarios by varying the distance between transmitter and receiver. We analyzed the performance of the network by using the intrusive technique of traffic injection with...
LTE-M, which is an abbreviated version of LTE-MTC(Machine Type Communication) can be said to have a variety of applications, including a large number of heterogeneous interconnection of large-scale network equipment. One of the most prominent problems is that the machines may have a large amount of access requests in a short time, which can easily lead to network congestion. At present, the contention-based...
The growing of the internet use is proportional with the growing of IP address needs, but the increasing of the IP use is not equal with the number of available IPv4. Then, IPv6 was developed as a solution to overcome the limited amount of IPv4 address. Readiness of various aspects ranging from infrastructure to a service provider is required to implement IPv6. In order to improve the quality of IPv6...
This paper focuses on proposing approaches for the improvement of Voice over Internet Protocol (VoIP) service quality in Wireless Mesh Network (WMN). While WMNs have self-healing, self-forming and dynamic topology features, they still pose challenges for the implementation of multimedia applications, such as voice, in various scenarios. The research has been conducted using a network simulator and...
Emergency nodes, i.e, nodes with priority 7 as per 802.15.6 standard play a very important role in facilitating the immediate transfer of information during life threatening situations. These nodes should relay critical information with utmost reliability and in the shortest possible time. IEEE 802.15.6 provides the necessary functionality to these nodes by adapting the contention window sizes as...
This paper investigates the problem of mean square finite-time passivity for discrete-time Markov jump neural networks with time delays and stochastic perturbations. In the measurement equation, a class of sensor nonlinearities are considered, which cover the standard Lipschitz condition as a special one. A sufficient mean square finite-time boundedness condition is established based on Lyapunov-like...
This paper presents the implementation of an active fiber optical-delay stabilization system in an optoelectronic oscillator. The primary use of the system is to stabilize optical point-to-point fiber links for synchronization purposes; however, the system can also be efficiently used as a stable optical delay line in an opto-electronic oscillator. By using a multipurpose optical delay stabilization...
The high-speed system and shrinkage in technology lead to more complexity with higher power dissipation. This paper presents the design, simulation and analysis of 6T, 7T and 8T SRAM cells. The analysis has been done for dynamic power, static power, rise time, fall time, delay, and bandwidth measurements for SRAM cells at gdpk180 technology. The Cadence Virtuoso tool is used for drawing schematic,...
The presence of metallic tubes and CNT diameter variation impacts delay of critical paths in CNFET circuits. Consequently, variations in critical path delays impact functional yield. We propose to predict circuit performance and yield using a statistical approach, rather than the worst-case method, to the critical path delay evaluation. We consider the CNT diameter variation and the number of tubes...

A new XNOR logic is designed using complimentary-metal-oxide semiconductor (CMOS) logic and Pass transistor logic. CMOS weak inverters improve the power consumption while pass transistors overcome voltage degradation problem. Carry logic is designed using transmission gates which...
This paper considers the boundary stabilization of stochastic delay reaction-diffusion systems(SDRDSs). We present the integral-form Lyapunov stability lemma for SDRDSs which provides the foundation of stability analysis for stochastic reaction-diffusion systems. Then, we design a boundary controller and obtain a criterion to guarantee the globally stochastically asymptotical stability of SDRDSs with...
