Linearization of power amplifier class AB using Cartesian feedback
Class AB power amplifiers are widely used in modern wireless communication systems. However, their non-linearity and high efficiency present a limitation to the performance of these systems. In this paper, we present one Cartesian feedback technique for linearizing AB power amplifier. We first demonstrate the analytical analysis of the proposed scheme, and then we validate the proposed technique using computer simulations. The amplifier parametric model used here takes into account actual operating characteristics of a real commercial unit used for multi carrier transmission.
