Abstract:
1. A power transistor comprising: a plurality of unit cell devices arranged along an axis, each unit cell device including a base portion, an emitter portion, and a collector portion; a base contact configuration including a first base feed and a second base feed, the first base feed being coupled to the base portion of each unit cell device via a first end of at least one base finger associated with a corresponding unit cell device and the second base feed being coupled to the base portion of each unit cell device via an opposite end of the at least one base finger associated with the corresponding unit cell device; an emitter contact configuration including a first emitter feed and a second emitter feed, the first emitter feed being coupled to the emitter portion of each unit cell device via a first end of an emitter finger associated with a corresponding unit cell device and the second emitter feed being coupled to the emitter portion of each unit cell device via an opposite end of the emitter finger associated with the corresponding unit cell device; and a collector contact configuration including a collector feed, the collector feed being coupled to the collector portion of each unit cell device.
