Abstract

One of the most significant figures of merit concerning a power amplifier is its effficiency. However, behavioral models of power amplifiers are mainly focused on functional aspects but not on current consumption. Therefore, simulations with respect to the efficiency of a power amplifier cannot be accomplished at system level. To close the gap of simulation capabilities, this article proposes a time efficient and accurate extension of behavioral models to predict current consumption. The current consumption model accounts for different bias conditions. For a commercial handset power amplifier, an average error of 1.9\% between the fast highlevel model and measurement results is obtained.
