Title: Method for modeling dielectric loss in transmission line
Inventor: BOYCE CARL J
IPC: G06F17/50
Filed: 2001-11-28
Abstract: PROBLEM TO BE SOLVED: To precisely perform modeling of a dielectric loss in transmission line even in a high frequency. SOLUTION: The method is disclosed which uses a software for modeling the dielectric loss in a computer chip or transmission line on a circuit board by using a circuit simulation application. A resistance, self-inductance and self capacitance of the line are calculated and modeled as a lumped element circuit having a resistance and inductor that are connected in series and a capacitance connected in parallel. The dielectric loss is modeled by using two-port scattering matrices. This method uses matrices associated with the dielectric constant of a medium surrounding the line, the overall length of the line and the frequency of a signal. This method assumes a typical low loss state of the circuit board or IC chip, by which the intrinsic impedance of the line is not affected by the loss and the matrix is normalized into the intrinsic impedance.
