Bonding-Wire-Geometric-Profile-Dependent Model for Mutual Coupling Between Two Bonding Wires on a Glass Substrate

The dependence of self-inductance and mutual inductance on bonding wire (BW) geometric profile has been studied in several papers. This paper will present a method using a BW-geometric-profile-dependent term to include this dependence in a simple model of BWs. The model element values will be calculated only from geometric dimensions. An experimental structure of two BWs in parallel planes has been fabricated based upon glass substrate technique for verification. A good agreement was obtained up to 8 GHz in comparison to electromagnetic simulation and measurement.
