Abstract
A system and method for limiting current in an output stage of power amplifier circuitry in a transmitter of a mobile terminal are provided. In general, the current in the output stage of the power amplifier circuitry is detected during each transmit burst from the power amplifier circuitry. For each transmit burst, an error correction value for a corresponding power level is determined based on the detected current and a predetermined threshold value. The error correction value is used to correct an adjustable power control signal that controls the power level of the power amplifier circuit for a subsequent transmit burst at the same power level.
