CONFIGURABLE POWER AMPLIFIER AND BIAS CONTROL

摘要

The bias control (300) selectively provides for bias of a power amplifier (120) based upon a bandgap voltage (442) generated by the bias control, or by a bias voltage external to the bias control. A controller (420) controls the selection of either the bandgap voltage (442) 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.
