This research aims to improve the accuracy of broadband transmission line models for high-speed digital systems.
Proposed a combination of time and frequency measurement data to address DC accuracy issues.
Introduced a new de-embedding technique to reduce reflection from port discontinuities.
Validated the method using several numerical examples, including MCM-L coplanar lines and package microstrip lines.
Demonstrated improved accuracy in time-domain simulations compared to traditional methods.
Showed that the new combination approach significantly mitigates DC errors and impedance characterization issues.
Validated the de-embedding technique with numerical examples that reflect the proposed method's efficacy.
