Abstract
The bias control selectively provides for bias of a power amplifier based upon a bandgap voltage generated by the bias control, or by a bias voltage external to the bias control. A controller controls the selection of either the bandgap voltage or external bias voltage. The bias control is fabricated in a first semiconductor material capable of operating at low voltage supply levels, such as complementary metal oxide semiconductor (CMOS) material and may be fabricated on an integrated circuit common with a power amplifier.
