“…It should be noted that the proposed circuit model on the basis of impedance parameters is simple in structure. What it needs is only one dependent source to represent the trans-impedance term between ports i and j, fewer than that of the equivalent circuit model in [6], which leads to efficiency in simulation. the currents of the N ports may be written in the form To demonstrate the validity of the method discussed in this paper, results from numerical studies have been presented.…”

A method for the analysis of simultaneous switching noise (SSN) on power distributions networks is developed. To alleviate the ill-conditioned matrix problem in constructing the macromodels of power distribution networks, the modified GramSchmidt orthogonal method is used to implement the matrix decomposition in QR form. Meanwhile a simple equivalent circuit model is presented for transient simulations, which results in efficiency in simulations. The simulation results have been analyzed to verify the validity of the proposed method.

“…The position of two pins is 0.5 mm away from the two corners. First, the time-domain responses associated with the extraction of the admittance parameters of the two-port structure are obtained using the quasi-three-dimensional FDTD modeling approach of [6]. A Gaussian pulse of 20dB bandwidth of 4 GHz is used as a voltage source at one port while the other port is short-circuited.…”

This paper presents a new methodology for synthesis of broadband equivalent circuits for multi-port high speed interconnect systems from numerically obtained and/or measured frequency-domain and time-domain response data. The equivalent circuit synthesis is based on the rational function fitting of admittance matrix, which combines the frequencydomain vector fitting process VECTFIT with its time-domain analog TDVF to yield a robust and versatile fitting algorithm. The generated rational fit is directly converted into a SPICEcompatible circuit after passivity enforcement. The accuracy of the resulting algorithm is demonstrated through its application to the fitting of the admittance matrix of a power/ground plane structure.

“…Examples include the finite difference time domain (FDTD) [28], [33], [44] method and frequency domain methods such as the transmission line method [31], cavity resonator [32], [34] method, transmission matrix method (TMM) [38], and integral equation method [37]. Since, package power distribution networks are resonant circuits with high quality factor, the frequency domain methods provide better accuracy and efficiency than the time domain methods.…”

Abstract-The power consumption of microprocessors isincreasing at an alarming rate leading to 2X reduction in the power distribution impedance for every product generation. In the last decade, high I/O ball grid array (BGA) packages have replaced quad flat pack (QFP) packages for lowering the inductance. Similarly, multilayered printed circuit boards loaded with decoupling capacitors are being used to meet the target impedance. With the trend toward system-on-package (SOP) architectures, the power distribution needs can only increase, further reducing the target impedance and increasing the isolation characteristics required. This paper provides an overview on the design of power distribution networks for digital and mixed-signal systems with emphasis on design tools, decoupling, measurements, and emerging technologies.
