A Unified Theory for Nonlinear Distortion Characteristics in Different Amplifier Technologies

This article presents a unified theory of power amplifier nonlinear distortion characteristics under small- and large-signal regimes for a wide range of active device technologies. It shows that some handy interactions between mild and strongly nonline...
RF power amplifiers (PA) are the last active blocks in any wireless transmitter system, handling the highest levels of RF signal and supply power. Linearization enforcing techniques relying on either adding external circuitry to the PA, or simply improving its design, 1 are thus necessary. However, since the first...
