The invention relates to a driver circuit ( 10 ) for integrated circuits comprising at least one input node ( 11 ) for an input signal and at least one output node ( 12 ) for an output signal. One or several, preferably two partial drivers ( 20, 30 ) supply approximately sine-wave shaped current to the load capacity ( 15 ) thereby improving electromagnetic compatibility. A feedback circuit ( 40 ) is also provided. Said feedback circuit consists of one or several evaluation circuits ( 50 ) and one or several feedback capacitors ( 41 ). The evaluation circuits ( 50 ) are connected to the partial drivers ( 20, 30 ) One feedback capacitor ( 41, 42 ) is respectively arranged between an output node ( 12 ) of the driver circuit ( 10 ) and an input node ( 51 ) of an evaluation circuit ( 50 ). An evaluation circuit ( 50 ) is provided via the feedback condenser ( 41, 42 ) between an output node ( 12 ) of the driver circuit and an input node ( 51 ). The edge steepness of the signal i.e. current which is independent of the actual load, can be produced by means of a feedback circuit ( 40 ). The feedback capacitor ( 41 ) can, for example, be embodied as a non-linear capacitor.
