Circuits and methods related to power amplifiers. In some implementations, a bias circuit includes a reference device connectable to receive a first electrical supply level, the reference device arranged to produce an electrical bias condition using the first electrical supply level, and the reference device connectable to provide the electrical bias condition to an amplifier device connectable to a second electrical supply level. The bias circuit also includes a power density translating circuit connectable between the reference device and the amplifier device, the power density matching circuit provided to substantially set a first power density associated with the reference device and a second power density associated with the amplifier device relative to one another, the first power density being a function of the first electrical supply level and the second power density being a function of the second electrical supply level.
