Abstract:
A system and method for biasing a power amplifier includes a power amplifier having a driver stage and an output stage, the driver stage having a plurality of driver devices, a bias current source configured to deliver a bias current to each of the plurality of driver devices, and a current directing element configured to receive the bias current and selectively bias each of the plurality of driver devices based on a reference voltage and a system voltage.
