A self-calibrating driver circuit () for a laser diode is disclosed. The circuit comprises a configurable current source (), a current mirror () configured to mirror a current from the configurable current source to a first transistor () and to a second transistor (), and a control circuit (). The control circuit is configured to monitor a current through the first transistor at a first time, and to configure the current source based on the current through the first transistor to provide a desired current to the second transistor for driving the laser diode at a subsequent second time. A radiation-emitting device comprising one or more of the self-calibrating driver circuits and at least one radiation-emitting element is also disclosed.
