Abstract
A circuit includes an electronic component package that comprises a first lead, a second lead, and a third lead; and a III-N transistor encased in the electronic component package, the III-N transistor including a drain, a gate, and a source, where the source is coupled to the first lead, the gate is coupled to the second lead, and the drain is coupled to the third lead. The circuit includes a high voltage node and a resistor, the resistor having a first terminal coupled to the high voltage node and a second terminal coupled to the third lead. The circuit further includes a ferrite bead connected in parallel to the resistor and coupled between the third lead and the high voltage node. When switching, the deleterious effects of a parasitic inductance of the circuit's power loop are mitigated by the ferrite bead and the resistor.
