ABSTRACT:
A first peaking current generating section generates a first peaking current in synchronism with the transitions of a digital signal, being positive at the rising edge and negative at the falling edge. A second peaking current generating section generates a second peaking current in synchronism with the transitions of the digital signal, being negative at the rising edge and positive at the falling edge. A first light emitting element driving section produces a first driving current obtained by combining together a signal amplitude current according to the amplitude of the digital signal and a first peaking current. A second light emitting element driving section produces a second driving current obtained by combining together the signal amplitude current according to the amplitude of the digital signal and a second peaking current. Then, the first and second light emitting element driving sections and drive the light emitting element by using a driving current obtained by subtracting the first driving current from the second driving current.
