Evaluation of concatenation techniques for state-space interconnect macromodels

In this work, we show that concatenating inter-connect models represented in state-space (descriptor) form, obtained from either the vector fitting algorithm or the Loewner matrix pencil method, can provide results as accurate as usual concatenation using sampled frequency domain data. A PCB-based interconnect is used as an example.
