Resumen
This thesis is dedicated to study differential transmission lines from an experimental
point of view. Thus, the results obtained here allow to obtain the
fundamental parameters of this type of lines through S-parameter data. In this
regard, one important contribution derived from this project was the proposal
of a methodology for obtaining four-port S-parameters associated with differential
transmission lines from a combination of two-port measurements without
requiring externally added terminations.
From the obtained information, it was possible to carry out an exhaustive
analysis of the characteristics presented by transmission lines in both frequency
and time domains, which is critical when assessing the performance of these lines
in actual interconnection channels. Furthermore, rigorous validations were performed
by correlating circuit models and measurements in time and frequency
domains. Besides, access to a four-port vector network analyzer allowed to verify
that the results obtained using the method proposed in this thesis correspond
to those obtained using more costly and measurement setups.
Therefore, this work represents a contribution in the signal integrity area by
providing circuit designers with effective tools for characterizing and modeling
differential transmission lines in a simple and straightforward way.
