Abstract
A filter circuit () is formed on a semiconductor substrate () formed with a trench () that is lined with a dielectric layer (). A conductive material () is disposed in the trench and coupled to a node () to provide a capacitance that modifies a frequency response of an input signal (V) to produce a filtered signal (V). An electrostatic discharge device includes an inductor () coupled to back to back diodes () formed in the substrate to avalanche when a voltage on the node reaches a predetermined magnitude.
