Abstract

This paper describes a novel, low cost active bias control configuration for a multi-carrier UMTS power amplifier. It consists simply of a detector and a gain-controlled op-amp, which tracks the envelope of an RF input signal to modulate the bias supply current to a standard monolithic amplifier. Simulation results indicate that power efficiency is improved and IMD level is reduced.
