CIRCUIT AND METHOD FOR COMPENSATING NON-LINEARITIES

Described are a circuit for compensating non-linearities essentially without changing a characteristic curve operating point and/or operating range, having: an alternating voltage signal source for providing an input signal; a control unit which receives the input signal and converts it to a predistorted signal depending on at least one preset predistortion parameter; and a sink for receiving the predistorted signal, the sink being coupled to an adjusting unit configured to provide the sink with an adjusting signal, to operate the sink in an operating range or at an operating point, the control unit being configured to receive at least one sensor signal of the sink in a feedback manner and to adapt the at least one preset predistortion parameter based on the at least one sensor signal, and a corresponding method.
