Abstract :
We discuss two control problems that arise in connection with Cartesian feedback radio-frequency power amplifiers. New solutions to both problems are described, and the results of a working prototype are presented. The prototype, a integrated circuit (IC) fabricated in National Semiconductor´s 0.25 /spl mu/m CMOS process, represents the first known fully integrated implementation of the Cartesian feedback concept.
