Patent ID: 7411450

Claim:
An amplification circuit comprising: a signal splitter supplied with an input signal that divides said input signal into a first partial signal and a second partial signal; a first signal path supplied with said first partial signal from said signal splitter, said first signal path comprising a first amplification stage that amplifies said first partial signal; a second signal path supplied with said second partial signal from said signal splitter, said second signal path comprising a second amplification stage that amplifies said second partial signal; a current supply that supplies current to each of said first and second signal amplification stages; a signal combiner connected downstream from said first and second amplification stages that re-combines the first and second partial signals, respectively amplified by said first and second amplification stages, to form an output signal; and a regulation device connected to each of said first amplification stage and said second amplification stage that regulates amplification of said first partial signal dependent on a current difference between a supply current requirement of the second amplification stage and a supply current requirement of the first amplification stage, and that regulates amplification of the second partial signal dependent on a difference between the supply current requirement of the first amplification stage and the supplied current requirement of the second amplification stage.
