Abstract

See full text

A method to generate a reduced delay twinaxial SPICE model is provided. The method may include measuring near-end S-parameter components and far-end S-parameter components of a twinaxial cable, reducing an original time delay of the far-end S-parameter components by multiplying each of the far-end S-parameter components by a complex exponential based on an equivalent delay length, a signal frequency, and an effective dielectric constant, simulating a signal transmitted across a twinaxial cable by running a 4-port SPICE model using the near-end S-parameter components and the multiplied far-end S-parameter components, and recording a magnitude and a phase of the transmitted signal with respect to frequency as outputs of the reduced delay twinaxial SPICE model.
