ABSTRACT:
A driver circuit including an amplifier, which generates a control signal from a reference signal; a driver current mirror; and a control current switch located between the amplifier and the driver current mirror which selectably isolates the driver current mirror from the amplifier or connects the driver current mirror to the amplifier, wherein the driver current mirror, when in a state connected to the amplifier, amplifies the control signal into a driver signal. A compensating circuit is provided that generates a correction signal, as a function of an error current of the driver current mirror and provides the correction signal to an input of the amplifier, wherein a feedback signal input of the amplifier is fed through a feedback path from a feedback signal coupled out of a control branch of the driver current mirror, and the compensating circuit additively provides the correction signal at an input of the amplifier.
