Driver circuit for electronic components

A driver circuit for electronic components comprising:

• an amplifier;
• a control current transistor which generates a control signal from a reference signal;
• a driver current mirror;
• a control current switch, which is provided between the control current transistor and the driver current mirror, and which selectably isolates the driver current mirror from the control current transistor or connects the driver current mirror to the driver current transistor, the driver current mirror, when in a state connected to the control current transistor, amplifying the control signal into a driver signal;
• and
• a compensating circuit provided between an input of the control current transistor and an input of the amplifier, the compensating circuit generating a correction signal and additively feeding the correction signal into the input of the amplifier
• wherein the driver current mirror has a control branch with a first transistor and a first emitter resistor, and also has a driver branch with a second transistor and a second emitter resistor,
• wherein GD is a conversion ratio,
• wherein a value of the second emitter resistor corresponds to 1/(the conversion ratio GD) times of a value of the first emitter resistor, and an emitter area of the second transistor corresponds to the conversion ratio GD times of an emitter area of the first transistor,
• wherein the compensating circuit has a proportional branch comprising a third transistor, a fourth transistor, a third emitter resistor of the third transistor, and a fourth emitter resistor of the fourth transistor, and wherein an input of the third transistor is connected to an input of the control current transistor, and
• wherein an emitter area of the third transistor is substantially equal to a quotient of an emitter area of the control current transistor in a numerator and a proportionality factor GC in a denominator, and wherein a value of the third emitter resistor is substantially equal to the proportionality factor GC times an emitter resistor which is connected in series between the control current transistor and a reference voltage connection.
