Abstract
A power transistor according to one embodiment of the invention includes a plurality of transistor elements located on a single semiconductor die, each transistor element comprising one or more transistors coupled to a common gate terminal for the respective transistor element. A resistor network couples the transistor element gate terminals between a bias voltage and a reference ground, with resistors in the network sized such that such that a first transistor element is biased in a first, e.g., class A, operating condition, and a second transistor element is biased in a second, e.g., class AB operating condition.
