ABSTRACT:
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.
