Abstract

See full text

A circuit includes an electronic component package that comprises at least a first lead, a III-N device in the electronic component package, a gate driver, and a ferrite bead. The III-N device comprises a drain, gate, and source, where the source is coupled to the first lead. The gate driver comprises a first terminal and a second terminal, where the first terminal is coupled to the first lead. The ferrite bead is coupled between the gate of the III-N transistor and the second terminal of the gate driver. When switching, the deleterious effects of the parasitic inductance of the circuit gate loop are mitigated by the ferrite bead.
