    Abstract: An integrated circuit common-mode electromagnetic interference filter incorporating electro-static discharge protection comprising two inductive coils is provided. A pair of primary and secondary spiral inductor coils is disposed corresponding to each other. A dielectric layer is used to separate the primary spiral inductor coil from the secondary spiral inductor coil electrically. Resistivity of a high-resistance substrate is more than 100 ?-cm for supporting the primary spiral inductor coil, the secondary spiral inductor coil and the dielectric layer thereon. The proposed filter structure can be formed in integrated circuit (IC) back-end processes and thus be extraordinarily advantageous of effectively eliminating electromagnetic interferences and having electrostatic protection effect at the same time, while having small footprint.
