ABSTRACT:
A drive current supply circuit is provided in which the speed of rise of the drive current to a laser diode is increased. In a drive current supply circuit for supplying drive current I to load50connected with the line1R of two parallel lines1R and2R of a first current mirror circuit1, this drive current supply circuit is provided with a control circuit CONT that controls the current i flowing in the other line1L in accordance with first control signal Σø1and the first control signal Σø1comprises a steady DC component øD and a drive signal component ø1added to the DC component øD when desired.
