Abstract:
A driver circuit, operating method, and use of a current mirror of a driver circuit is provided that includes at least one output transistor, a reference network with at least one reference transistor, a switching device, which is connected to the control input of the output transistor and to the control input of the reference transistor to form a switchable current mirror, a current source for providing a reference current for a reference current path, whereby the current source and the reference transistor are arranged in the reference current path, a load terminal, whereby the load terminal and the output transistor are arranged in a load current path, and at least one damping network, which is connected to or connectable to the reference current path. Wherein a connection of components of the at least one damping network and a connection of components of the reference network are substantially the same.
