Frequency domain behavior of S‐parameters piecewise‐linear fitting in a digital‐wave framework

Abstract This paper describes PWLFIT+, an extension to the frequency domain of PWLFIT, a new paradigm in time‐domain macromodeling for linear multiport systems, based on a piecewise‐linear (PWL) behavioral representation of the S‐parameters step response. While the impulse response of each S‐paramet... View More
