FinFETs are very promising for integrated circuit low signal anolog applications. In this paper we present, non-linear analysis of this type of devices using technology CAD (TCAD), which complements the already done studies about the advantages and possibilities of source/drain extension (SDE) engineering of FinFET for anolog applications. This is a simple and fast way to predict linearity using TCAD at an early stage FinFET design process. The method is based on time domain waveforms at drain and gate terminals at different input power level. By carrying out spectrum analysis of time-domain signals and knowing fundamental power Pfund and third order harmonics ( IM3 ) power at different input power have been used to determine third-order intercept ( IP3 ). The value of IP3 obtained using approach is found to ∼4dBm at Vg = 0.25V and Vd = 1.1V . Further on Vg is varied at fixed Vd = 1.1V , and effect of Vg on 3 fund IM3 / Pfund is investigated.

The paper is devoted to problem of spline approximation. A new method of nodes location for curves and surfaces computer construction by means of B-splines and results of simulink-modeling is presented. The advantages of this paper is that we comprise the basic spline with classical polynomials both on accuracy, as well as degree of paralleling calculations are also shown.

This paper. presents a method for objects detection and features extraction in static video imagery that operates on color/gray-scale frames grabbed by common digital cameras or readily available images from external sources. Segmenting objects is achieved by a technique proposed here and named as direct thresholding (DTh) with background extracted through applying morphological background estimation scheme (MBES). The accommodating hardware is represented by a dedicated P4 PC-based image processing environment, whereas the intrinsic software has been simulated and validated using MATLAB7.3 platform. Human visual perceptual inspection plus histogramming showed an appreciable level of performance through a specific experimentation of multiple-phases. The envisaged diverse fields of application of this method may involve: traffic flow measurement of vehicles and pedestrians; athletic and dancing performance evaluation; public, private, and military security, and so on.

In this paper, a multicarrier frequency hopping spread spectrum (MCFH-SS) system with girth-six low-density parity-check (LDPC) codes is developed as forward error correction scheme to improve its anti-jamming (AJ) capabilities. The paper also evaluates the bit error rate (BER) of girth-six LDPC codes with a column weight 3 for the given values of fractional bandwidth (ρ). It is found that the performance of MCFH-SS system with LDPC codes is significantly better than the system employing fast frequency hopping spread spectrum (FFH-SS) with girth-six LDPC codes in the presence of partial band noise jamming (PBNJ) over Additive White Gaussian Noise (AWGN) channel. At ρ =1, the BER of MCFH-SS and FFH-SS system is approximately 10−3 and 10−2 , respectively. This shows the effectiveness of MCFH-SS system with girth-six LDPC codes.

Field programmable gate arrays (FPGAs) have emerged as platform of choice for efficient hardware realization of computation intensive algorithms because of their intrinsic parallelism and flexible architecture. However, to achieve high performance, FPGA must be supported by efficient design methodology and optimization techniques. In this paper, FPGA-based design methodology and optimization techniques that can be employed to obtain area, speed and power efficient circuits are reviewed and presented.

High transmission bit rate in futuristic mobile channels gives rise to severe ISI and this makes the detection task very challenging. Thus a smart detector such as Near Maximum Likelihood (NML) detector is needed and is the subject of study in this paper. Performance assessment of near-optimal NML detectors over such channels assumes great importance. Variation in performance of NMLD using different delays in detection has been assessed in terms of BER versus SNR curves. A number of different cases of mobile radio channels have been simulated in this work. These channels have different number of reflected paths with equal power distribution in the respective paths. The aim of this paper is to take a ‘worst case’ model of a mobile radio channel and then to investigate the performance of detectors in the receivers.

CDMA is interference limited multiple access system. Power control is an effective way to reduce co-channel interference. Consequently, it can improve the system capacity. CDMA employs fast closed-loop power control in uplink in which signal-to-interference ratio (SIR) is estimated. Transmitting power is adjusted by comparing estimated SIR with desired SIR. In this paper a modified fixed step power control algorithm has been proposed, which can improve the performance of a CDMA system. The proposed algorithm produced a faster convergence and low outage probability compared to other power control algorithms discussed and analyzed to maintain the desired SIR target.

In this paper, a comparative study of JPEG and SPIHT compression algorithms is presented. A set of objective picture quality measures like Peak Signal to Noise Ratio (PSNR), Maximum Difference (MD), Least Mean Square Error (LMSE), Structural Similarity Index (SSIM) and Picture Quality Scale(PQS) are used to measure the picture quality and comparison is done based upon the results of these quality measures. Different kind of standard test images are assessed with different compression ratios. SPIHT based compression achieves better results as compared to JPEG for all compressions.

The purpose of this project is to design and build a control system with an FPGA chip to control the movements of a robotic arm. The whole system is composed of the Controller System and the drive circuits, one driver circuit for each motor on the robotic arm. These drive circuits are needed because the Control System does not supply enough power to drive the motors directly. The controller System is implemented on the Spartan -II FPGA chip using VHDL code. Spartan -II FPGA is capable of running at much higher speed but a slow clock is needed to obtain relatively large delays for the output signals. This paper basically focus on the work of our project which is based on motion control using stepper motor .we have successfully done the basic part of project in which we control the stepper motor using FPGA. We have successfully done the programming and simulation part of the project. We enjoyed the PCB designing, soldering and troubleshooting of PCB. This project gives the idea regarding controlling servo and stepper motor using interfacing of ULN2803A with FPGA. Consequently, it's important to understand how to work, and what problems exist in designing effective robots. This project will address one of those problems: positional control.
