Abstract
Illustrative apparatuses and methods for electrostatic discharge protection are described in which the frequency of a voltage received at a first circuit node is filtered to generate a filtered voltage, one or more control signals are generated having either a first voltage or a second voltage depending upon the value of the filtered voltage, and the first circuit node is selectively connected with a second circuit node depending upon the value of the one or more control signals.
