ABSTRACT:
A driver circuit for a laser diode includes a prebiasing amplifier for providing a prebiasing current, a second amplifier for amplifying an input signal to provide an output current signal, and a third amplifier for amplifying the sum of the current output signal and the prebiasing current. In one embodiment, the third amplifier includes first and second current mirrors. In another embodiment, a capacitor couples one output of the second amplifier to an inverting input of the third amplifier, so as to increase the effective gain of the third amplifier.
