These are determined by the ratio of mutual capacitance to self-capacitance, and mutual inductance to self-inductance. Quantitatively, this energy results from mutual inductances and capacitances in the Telegrapher’s Equations:Ĭrosstalk is often discussed in terms of forward and backward crosstalk coefficients. Crosstalk magnitude is dependent on risetime, signal line geometry and net configuration (type of terminations, etc.). Impedance reflection across a boundaryĬrosstalk is undesired energy imparted to a transmission line due to signals in adjacent lines. The voltage reflection coefficient, (Z1-Z0)/(Z1+Z0) is a measure of this mismatch:įigure 2. The amount of energy reflected depends on the degree of impedance mismatch. When a voltage step is traveling down a uniform impedance transmission line, and then encounters an abrupt change in impedance, a portion of the incident energy is “reflected” back. Delay And Dielectric Constants For Some Transmission Lines For a uniform, lossless transmission line. Where c is the speed of light, and er is the relative dielectric constant. The propagation delay is the reciprocal of the phase velocity multiplied by the length of the transmission line: The attenuation constant is the real part of the propagation constant and is important when losses must be considered.
If R and G are zero, the characteristic impedance will not depend on frequency, and reduces to
Line, it is invariant with respect to time and position on the line: The characteristic impedance of a transmission line is the ratio of the voltage to the current. This section presents the basic concepts of characteristic impedance and propagation delay, and reflections and crosstalk. This article provides information for the two center blocks, by discussing relevant devices and models in PSpice, along with specific modeling techniques and examples. Analysis flowchart for transmission line nets These steps are given in the following flowchart:įigure 1. The analysis of transmission line nets requires multiple steps. It is the purpose of this article to examine the steps and issues involved in modeling and analyzing transmission lines in PSpice. For analog circuits, the frequency response of circuits with transmission lines can be analyzed. For analog and digital circuits, there is a need to examine signal quality for a printed circuit board and cables in a system. OrCAD PSpice contains distributed and lumped lossy transmission lines that can help to improve the reliability of many applications. Transmission lines are used for varied applications, including: This app note illustrates the steps and issues involved in modeling and analyzing transmission lines in PSpice. These phones diagram are the examples of mobile schematic diagram.Transmission lines are used to propagate digital and analog signals, and as frequency domain components in microwave design. with the help of all mobile circuit diagram in pdf, they can trace lines and find where particular components on a mobile phone PCB.
