This book was released on 2011 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accurate measurement technique is required to fully characterize the losses observed at high frequencies in transmission lines. Evaluation of losses seen at high frequencies is necessary to meet the high-speed data transfer rates that future applications will demand. Conductor properties and losses are two critical issues in signal path characterization. The nature of conductor losses is not well understood at high speeds. Classical models used for predicting the effects of surface roughness on signal propagation are known to breakdown around 5 GHz. Novel methods are sought to quantify the effects beyond 5 GHz. Direct simulation and measurements of surface roughness effects are difficult, because dielectric loss has similar impact on measured data. In this study, the phenomenon of copper surface roughness will be addressed. A novel methodology to extract conductor based on a stripline configuration of two different widths will be proposed. This new methodology does not suffer from inaccurate assumptions on the dielectric loss tangent as the contribution of the dielectric loss is completely eliminated. Simulation will be performed using ANSYS HFSS and AGILENT ADS. The final outcome of this thesis will be to verify electromagnetic simulations with surface roughness against measurements and to demonstrate the importance of surface roughness.

Download or read book Lossy Transmission Line Modeling and Simulation Using Special Functions written by and published by . This book was released on 2006 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new algorithm for modeling and simulation of lossy interconnect structures modeled by transmission lines with Frequency Independent Line Parameters (FILP) or Frequency Dependent Line Parameters (FDLP) is developed in this research. Since frequency-dependent RLGC parameters must be employed to correctly model skin effects and dielectric losses for high-performance interconnects, we first study the behaviors of various lossy interconnects that are characterized by FILP and FDLP. Current general macromodeling methods and Model Order Reduction (MOR) algorithms are discussed. Next, some canonical integrals that are associated with transient responses of lossy transmission lines with FILP are presented. By using contour integration techniques, these integrals can be represented as closed-form expressions involving special functions, i.e., Incomplete Lipshitz-Hankel Integrals (ILHIs) and Complementary Incomplete Lipshitz-Hankel Integrals (CILHIs). Various input signals, such as ramp signals and the exponentially decaying sine signals, are used to test the expressions involving ILHIs and CILHIs. Excellent agreements are observed between the closed-form expressions involving ILHIs and CILHIs and simulation results from commercial simulation tools. We then developed a frequency-domain Dispersive Hybrid Phase-Pole Macromodel (DHPPM) for lossy transmission lines with FDLP, which consists of a constant RLGC propagation function multiplied by a residue series. The basic idea is to first extract the dominant physical phenomenology by using a propagation function in the frequency domain that is modeled by FILP. A rational function approximation is then used to account for the remaining effects of FDLP lines. By using a partial fraction expansion and analytically evaluating the required inverse Fourier transform integrals, the time-domain DHPPM can be decomposed as a sum of canonical transient responses for lines with FILP for various excitations (e.g., trapezoidal and unit-step). These canonical transient responses are then expressed analytically as closed-form expressions involving ILHIs, CILHIs, and Bessel functions. The DHPPM simulator can simulate transient results for various input waveforms on both single and coupled interconnect structures. Comparisons between the DHPPM results and the results produced by commercial simulation tools like HSPICE and a numerical Inverse Fast Fourier Transform (IFFT) show that the DHPPM results are very accurate.

Download or read book Scattering Parameter Transient Analysis of Transmission Lines Loaded with Nonlinear Terminations written by J. E. Schutt-Aine and published by . This book was released on 1987 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents a new approach for the time domain simulation of transients on a dispersive and lossy transmission line terminated with active devices. The method combines the scattering matrix of an arbitrary line and the nonlinear causal impedance functions at the load to derive a closed form algorithm for the signal at the near and far ends. The problems of line losses, dispersion and nonlinearities are first investigated. A time-domain formulation is then proposed using the scattering matrix representation. The algorithm assumes that dispersion and loss models for the transmission lines are available and that the frequency dependence is known. Large signal equivalent circuits for the terminations are assumed to be given. Experimental and computer simulated results are compared for the lossless dispersionless case, and the effects of losses and dispersion are predicted.

Book Synopsis Scattering-theory-based Methodology for Electromagnetic Transient Analysis of Nonuniform Frequency-dependent Transmission Line Structures by : Manuja Gunawardana

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overhead transmission lines are a vital component in electrical power networks. Overvoltage transients that originate in transmission lines due to disturbances such as lightning or switching can reach other components in a power system and create electrical insulation breakdown and equipment failure if countermeasures are not sufficiently taken. Therefore, accurate electromagnetic transient (EMT) modelling of the transmission line network is an essential requirement in designing and analyzing a power system. The increasing demand for electrical power and limited availability of land has caused overhead power transmission lines to be constructed in close proximity to each other. These close encounters such as nonparallel lines in close proximity, ultra-high voltage (UHV) lines crossing above lower voltage lines, communication lines or buried pipelines, and discontinuities such as lines undergoing sharp bends are generally nonuniform in nature. Several researchers have shown that the transient behaviour of transmission lines with such nonuniformities is far from what is predicted using conventional transmission line models that assume a uniform cross-sectional structure. Although three dimensional full-wave techniques can be used to accurately analyze these non-uniform structures, they are often associated with high computational costs and typically require iterative methods to obtain solutions. This makes them hardly suitable for circuit-type time-domain simulations. This research is focused on developing computationally efficient and EMT-simulator compatible time-domain models to analyze the transient behavior of nonuniform transmission problems involving nonparallel conductors. Transient models for both overhead and buried nonuniform structures have been derived and successfully implemented on an EMT simulator (PSCAD/EMTDC). Higher computational efficiency has been achieved by developing closed-form mathematical models which can be solved using lesser number of computations than full-wave models as well as by using parallel computing techniques. Results have been compared with those obtained using full-wave solvers and field measurement obtained by other researchers available in the literature.

This book was released on 2002 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Differential circuits are becoming increasingly important in radio frequency (RF) and microwave applications. This has led to the development of mixed-mode scattering parameters to address differential and common-mode operations. Mixed-mode scattering parameters also address the conversion between the two modes of operation. In the measurement or in the modeling of any differential circuits, it is found that a pure-mode network-analyzer provides accurate measurements of differential circuits. Additionally, given the standard S-parameters (either by measurements or by modeling), we can apply a conversion from standard S-parameters to mixed-mode S-parameters. Furthermore, to guarantee the accuracy of the S-parameters derived from the measurement by the network analyzer, a proper calibration method and an appropriate type of system error model must be carefully considered. In this thesis, several different normal calibration standards, including TRL, TRL*, TRM and TRM*, and their related error models are analyzed. Single-ended and mixed-mode S-parameters can be further processed to generate time domain eye patterns, so as to characterize signal loss and attenuation through RF devices and interconnects. The method of eye pattern generation is discussed and some samples of eye patterns for different high data-rate transmissions are presented. Another part of the thesis details the modeling of frequency-dependent losses on transmission lines. A methodology for extracting the dielectric constant and loss tangent of the PCB substrate is demonstrated using stripline test structures. Some works on transmission line characterization and cross-section analysis are also discussed"--Abstract, leaf iii.

Download or read book Transmission Lines and Lumped Circuits written by Giovanni Miano and published by Elsevier. This book was released on 2001-02-23 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of transmission lines is a classical topic of electrical engineering. Recently this topic has received renewed attention and has been a focus of considerable research. This is because the transmisson line theory has found new and important applications in the area of high-speed VLSI interconnects, while it has retained its significance in the area of power transmission. In many applications, transmission lines are connected to nonlinear circuits. For instance, interconnects of high-speed VLSI chips can be modelled as transmission lines loaded with nonlinear elements. These nonlinearities may lead to many new effects such as instability, chaos, generation of higher order harmonics, etc. The mathematical models of transmission lines with nonlinear loads consist of the linear partial differential equations describing the current and voltage dynamics along the lines together with the nonlinear boundary conditions imposed by the nonlinear loads connected to the lines. These nonlinear boundary conditions make the mathematical treatment very difficult. For this reason, the analysis of transmission lines with nonlinear loads has not been addressed adequately in the existing literature. The unique and distinct feature of the proposed book is that it will present systematic, comprehensive, and in-depth analysis of transmission lines with nonlinear loads. A unified approach for the analysis of networks composed of distributed and lumped circuits A simple, concise and completely general way to present the wave propagation on transmission lines, including a thorough study of the line equations in characteristic form Frequency and time domain multiport representations of any linear transmission line A detailed analysis of the influence on the line characterization of the frequency and space dependence of the line parameters A rigorous study of the properties of the analytical and numerical solutions of the network equations The associated discrete circuits and the associated resisitive circuits of transmission lines Periodic solutions, bifurcations and chaos in transmission lines connected to noninear lumped circuits
