A method in an amplifier, for example, a power amplifier in a wireless transmitter, including monitoring ( 310 ) a characteristic of the amplifier during a first active interval of the first set of active intervals, storing ( 320 ) the amplifier characteristic monitored during the first active interval of the first set of active intervals, correcting ( 340 ) an open-loop control signal to the amplifier based on the stored amplifier characteristic monitored during the first active interval of the first set of active intervals, and providing ( 350 ) the corrected control signal during a second active interval of the set of first active intervals subsequent to the first active interval of the set of first active intervals.
