摘要： A driver circuit and a method drive an electronic component such as a laser diode with a variable electric current that is controlledly switched between at least two discrete current levels. The driver circuit includes circuit elements that damp ringing or initial transient oscillations that arise when switching the current between the current levels. The driver circuit includes a current mirror having a mirror amplification factor dependent on the frequency of the variable electric current. In order to counteract parasitic capacitances and/or inductances leading to the ringing, an inductance and/or a resistance are connected between the two series circuits making up the current mirror, a capacitance is connected parallel to a reference resistor of one of the series circuits, and/or a capacitance is connected across the voltage supply.

摘要： A driver circuit is provided, which includes a differential amplifier whose output signal controls the driving input signal, a reference signal generator that supplies a reference input of the differential amplifier, an external feedback that applies a signal, which is dependent on the output signal, to a feedback input of the differential amplifier, an adapter circuit, and an internal feedback activated in a compensation mode as an alternative to the external feedback, which internal feedback provides a signal to both the feedback input and the adapter circuit even for input signals that do not exceed the first threshold. The adaptor circuit generates and stores a compensation signal that compensates an offset signal acting alone at the reference input when the reference signal generator is switched off, and feeds the stored compensation signal, together with a reference signal, to the reference input or feedback input when the external feedback is activated.
