An integrated circuit device comprises at least one non-linear circuit. Further the integrated circuit device comprises a plurality of terminal circuits coupled to the non-linear circuit. Each terminal circuit comprises an associated terminal and an inductor coupled to the associated terminal and to the at least one non-linear circuit. A protective device for protection of a circuit, comprises an electro-static discharge protection element configured to be coupled to a circuit terminal and an inductor coupled to the electro-static discharge protection element and configured to be coupled to the circuit. The inductor has a low quality factor.
