RF TRANSMITTERS WITH SATURATION DETECTION AND CORRECTION AND METHODS THEREFOR

摘要

Methods in radio communications devices having a transmitter with an integral control loop, and in other integral control systems, including generating a first error signal (210) based upon an amplifier output signal and a corrected reference signal, generating a second error (220) signal based on a closed loop integral control signal applied to a control input of the amplifier and based on an integral control reference signal, and generating the corrected reference signal (230) by correcting a reference signal based upon the first and second error signals.
