1. A system, comprising:
a signal input;
a predistortion circuit; and
an amplifier circuit,
the predistortion circuit being operatively coupled to the signal input and to the amplifier circuit and configured to modify a radio frequency (RF) signal received at the signal input to cause the amplifier circuit to drive, into a load connected to the amplifier circuit, a current that is substantially a replica of the input signal.
