Hierarchical modeling of a 2.4-GHz power amplifier for energy consumption analysis at system level

In this paper the hierarchical modeling of a 2.4-GHz RF power amplifier with its energy consumption considerations is presented. The models foresee the component´s total power consumption as one of its high-level parameters, in addition to gain, input and output impedances and third order nonlinearities. Hence an estimation of the energy consumed by the transmitter can be achieved at the system level of design, due to the inclusion of amplifier´s efficiency (¿), first within an intermediate model (VHDL-AMS) and later at highest level, using Matlab and Simulink.
