Abstract
Various apparatuses and methods for varying segment activation in a segmented power amplifier are disclosed herein. For example, some embodiments provide a power amplifier including an input, an output, a plurality of amplifier segments and a controller. The amplifier segments are connected in parallel between the input and the output and are adapted to be activated and inactivated. The power level at the output may be controlled by changing a number of the amplifier segments that are activated concurrently. The controller is connected to the amplifier segments and is adapted to vary which of the amplifier segments are activated to arrive at a selected number of activated amplifier segments.
