Abstract
A driver circuit which has one or more driver transistors connected to a load and which further includes at least one circuit block configured to control the voltage on the gate nodes of the one or more driver transistors and which is connected to the latter. The gate source voltage of the one or more driver transistors can be controlled, using an appropriate configuration of the circuit blocks in relation to the circuit, by the application of the current in such a way that the charging/discharging current is approximately sine. The circuit block has a current source that controls the gate voltage on the gate nodes of the one or more driver transistors and the circuit block as an additional first voltage source that provides the operating voltage of the driver circuit, in addition to a second voltage source that provides a control voltage which is used to adapt the driver circuit to different load magnitudes.
