Abstract :
A new algorithm is introduced for broadband macromodelling of passive electronic components from frequency response data. It modifies the vector fitting algorithm in such a way that the L1 norm of the approximation error is minimised, rather than the L2 norm. It is shown that this approach is more robust towards outliers in the data.
