Abstract
A reconfigurable power amplifier (PA) is studied in this paper, dedicated to multi-mode, multi-standard radio frequency front-end (RFFE), from a low cost approach. The reconfigurable amplifier topology is presented, made up of two-stages independently controllable by the biasing scheme proposed which allows the dynamic modification of the quiescent current of the RF transistor, to adapt both its linearity and its output power in order to fulfill different standards specifications.
