Abstract

An additional control voltage is used to adjust then operating point of a power amplifier. The amplitude of the control voltage is a measure of the maximum gain needed during the current time slot and which is already provided to the power amplifier before the beginning of the active time slot. This enables an individual adjustment of the operating point so that the power consumption can be reduced.
