Claim Text:
1. An electrostatic discharge protection circuit, comprising: a first LC resonator circuit coupled to an input node and disposed in parallel with an internal circuit that is also coupled to the input node, the first LC resonator including a second LC resonator circuit coupled in series with the first LC resonator circuit at a first node, the second LC resonator including wherein the first LC resonator circuit is configured to resonate at a different frequency than a frequency at which the second LC resonator circuit is configured to resonate, and a first connecting end portion of the first portion of the single planar inductor is disposed in a first metal layer and second connecting end portion of the second portion of the single planar inductor is disposed in a second metal layer, wherein the first connecting end portion does not contact the second metal layer and the second connecting end portion does not contact the first metal layer.
