Characterization and modeling of crosstalk noise in digital systems and microwave applications

This dissertation presents the characterization and modeling of crosstalk noise based on the theory of coupled microstrip lines. An equivalent circuit model used in this work comprises of the addition of mutual inductances and mutual capacitances to the fundamental transmission line model. Characterization of crosstalk noise along adjacent lines, current-voltage characteristics, characteristic impedance, effective dielectric impedance, and maximum crosstalk are performed analytically. Computer simulations and computations of these parameters are also performed. The circuits are realized experimentally, and an investigation of crosstalk noise using time domain and frequency domain measurement techniques is conducted. The results illustrate that the computation matched closely the experimental data and explained the physical phenomena better.
