The paper presents the effect of conductive or lossy silicon (Si) substrates on the frequency-dependent distributed series impedance transmission line (TL) parameters, R(ω) and L(ω). The frequency variations of these parameters of the microstrip line for four different conductivities of Si substrate are observed and compared.

| Interconnect in VLSI circuits is best modeled as a lossy transmission line in high speed integrated circuits. Analytical expressions for the coupling noise between adjacent interconnect are presented to estimate the peak noise voltage on a quiet line based on the assumption that these interconnections are loosely coupled, where the e ect of the coupling noise on the waveform of an active line...

|Interconnect between a CMOS driver and receiver can be modeled as a lossy transmission line in high speed CMOS VLSI circuits as transition times become comparable to or less than the time of ight delay of the signal through the interconnect. In this discussion, a linear resistor model is used to approximate the CMOS driver stage, and the CMOS receiver is modeled as a capacitor. A closed form e...

Abstract— In this paper, input impedance of a vertical rod under lightning stroke is first computed by applying the method of moments (MoM) on the Maxwell’s equations. The circuit model is then achieved through applying modified vector fitting (MVF) on the computed input impedance. After then the equivalent circuit is again extracted for a few values of soil conductivity and rod radius. Finally...

The problem of terminating a transmission line that consists of a set of coupled loop resonators to support the propagation of magneto-inductive waves is considered. Since the ideal terminating impedance is not easily realisable end-reflections are generally obtained from such a line. Techniques are developed to calculate the reflection coefficient from a line terminated with a finite number of...

this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...

In this paper, we will present a low losses multiconductor transmission lines model valid both in the time and the frequency domains. This model is an extension of the characteristics method (Branin method) valid for lossless lines. Our model permits to describe the line as a quadripole whose advantage is to avoid the presupposed applied charges conditions in its extremes. This permits it to be...
