Abstract

An electrostatic discharge protection circuit includes 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, and a second LC resonator circuit coupled in series with the first LC resonator circuit at a first node. The first LC resonator circuit is configured to resonate at a different frequency than a frequency the second LC resonator circuit is configured to resonate.
