Abstract :
Fosters´ canonical representation of the transfer characteristic of a linear system is the key to causal fully convergent incorporation of distributed structures in transient circuit simulators. The implementation of the Foster´s model in the fREEDA circuit simulator is reported and the modeling of a two-port coupled inductor is presented as an example.
