Classification: CPC H | IPC H

Claim 18:
19. A digital predistortion (DPD) system, comprising:
an input configured to receive an input signal;
a first signal path configured to generate a first signal based on the input signal;
an error model provider configured to generate an error model signal modeled after a gate bias error voltage of associated with the DPD system;
a first combiner configured to combine the first signal and the error model signal to generate a first intermediate signal;
an output signal based at least on the first intermediate signal;
a first plurality of combiners configured to generate a plurality of powers of the error model signal;
a first plurality of signal paths configured to generate a first plurality of signals based on the input signal; and
a second plurality of combiners configured to combine each of the first plurality of signals with a respective one of the plurality of powers of the error model signal to generate a first plurality of intermediate signals;
wherein the output signal is also based the first plurality of intermediate signals.
