Beschreibung
Zusammenfassung:A semiconductor device includes a first transistor, a second transistor coupled in parallel with the first transistor, and a first parasitic inductance between an emitter of the first transistor and an emitter of the second transistor. The semiconductor device includes a first circuit configured to provide a first gate driver signal to the first transistor based on a common driver signal and a second circuit configured to provide a second gate driver signal to the second transistor based on the common driver signal. The first circuit and the second circuit are configured to compensate for a voltage drop across the first parasitic inductance such that the first gate driver signal and the second gate driver signal are in phase with and at the same magnitude as the common driver signal.
