Abstract
Many embodiments of the invention include stacked power amplifier configurations that include control circuitry for sensing the operational characteristics of the power amplifiers and adjusting the current drawn by one or more of the power amplifiers to prevent any of the power amplifiers from experiencing over voltage stresses and/or to increase the operational efficiency of the power amplifiers.
