The Skyworks Capacitor model for ESD applications is described and discussed. A Skyworks ESD Capacitor is modeled as an ideal capacitor in parallel with a leakage current source, along with a resistor to the ground modeling the substrate leakage at each terminal. The current-voltage and small-signal characteristics predicted by the model coincide with measurement results. Furthermore, by employing the human body model (HBM), an ESD simulation environment is set up in order to simulate ESD tests on Skyworks ESD Capacitors. The breakdown criteria of two kinds of Skyworks ESD Capacitors are investigated and the corresponding model is investigated and developed based on experimental data.
