  • Based on the vector fitting principle and circuit theory, a kind of active integrated device wideband circuit modeling methods for electromagnetic magnetic compatibility(EMC) simulation was proposed. The port parameters in DC bias obtained by measurements using vector fitting method were transformed into pole-residue and time domain state equation model; then a circuit netlist model which compatible with simulation program with integrated circuit emphasis(SPICE) was obtained, the netlist can replace the target chip used in circuit simulation. Finally, this method was used for sample chip power distribution network(PDN) module and was compared with the IC electromagnetism modeling(ICEM) modeling. The results show that the vector fitting model has a wider bandwidth and smaller model errors.
