Abstract
A current control device for a differential circuit is provided. The current control device includes a differential circuit that generates differential signals comprising a positive signal and a negative signal in opposite phases, an amplitude detection circuit detecting an amplitude of the differential signal and outputting first and second detection voltages, an error amplification circuit controlling the differential circuit on the basis of an error voltage between the first and second detection voltages, and a current control circuit controlling the amplitude detection circuit on the basis of any one of the first and second detection voltages.
