<p>There is disclosed a method of generating a supply voltage (230) for a power amplifier (114) arranged to amplify an input signal (228), comprising: generating (104) a target supply voltage tracking the input signal (228); predistorting (400) the target supply voltage to compensate for effects on a supply voltage in the amplifier (114); and generating (102) the supply voltage for the amplifier (114) in dependence on the predistorted target supply voltage (414).</p> |
