ABSTRACT:
A peaking current generating section generates a spire-shaped peaking current that is in synchronism with the transitions of the digital signal, at the rising edge and the falling edge. A light emitting element driving section produces a driving current obtained by combining together a signal amplitude current according to the amplitude of the digital signal and the peaking current. Then, the light emitting element driving section drives a light emitting element by using the driving current. A signal analysis section analyzes the digital signal so as to set a control signal based on the pulse width of the digital signal. A clipping section clips the peaking current of the driving current according to the control signal set by the signal analysis section.
