Abstract :
A method for the computation of a reduced order circuit model, based on the approximation of |Y(jomega)| with a set of assymptotes corresponding to a simple RC admittance is presented. The circuit passivity is preserved unlike the majority of other approaches. A 1033 node RC circuit is reduced to admittance with one pole and two zeros for a frequency range of three decades
