Abstract
Techniques are provided for dynamically biasing an amplifier to extend the amplifier's operating range while conserving power. In an embodiment, a detector is provided to measure the amplifier output to determine an operating region of the amplifier. The output of the detector may be input to a bias adjuster, which outputs a dynamic voltage level supplied to at least one bias transistor in the amplifier. Multiple embodiments of the detector and bias adjuster are disclosed.
