ABSTRACT:
A method of adapting parameters for a predistortion circuit in an integrated circuit is disclosed. The method comprises receiving, at the predistortion circuit, an input signal to be amplified by a power amplifier; determining a value associated with an information tag for the input signal; applying parameters to the predistortion circuit based upon the determined value; receiving an output of the power amplifier at an input of the integrated circuit; comparing an output of the predistortion circuit with the output of the power amplifier; and generating updated parameters to be applied to the predistortion circuit. An integrated circuit having a circuit for adapting parameters for a predistortion circuit of the integrated circuit is also disclosed.
