Abstract
In a circuit and a method for amplification of an electrical input signal, a signal splitter divides the input signal into a first partial signal in a first signal path and a second partial signal in a second signal path. The first signal path has a first amplification stage for amplification of the first partial signal and the second signal path has a second amplification stage for amplification of the second partial signal. Each of the two amplification stages is supplied with current by a current supply device. Both amplified partial signals are recombined into an output signal by a signal combination element downstream from the amplification stages. The first amplification stage and the second amplification stage are coupled with a regulation device that regulates the amplification of the 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 which regulates the amplification of the second partial signal dependent on a current difference between the supply current requirement of the first amplification stage and the supply current requirement of the second amplification stage.
