The Need for Impulse Response Models and an Accurate Method for Impulse Generation from Band- Limited S-Parameters

2 In the signal integrity industry, S-parameters have become the most commonly distributed models for simulating passive components. Because S-parameters are frequency-domain values, many signal integrity engineers are finding it difficult to accurately implement these parameters in time-domain simulations. Addressing transient convolution specifically, this paper shows the need for a new impulse response model and proposes a methodology for its inclusion in time-domain simulations. The paper also solves another difficult problem by presenting a new technique for converting band-limited S-parameters into ‘base-delay ’ causal and passive impulse response models that preserve accuracy to the maximum frequency of the original S-parameters.
