Abstract:
     A current source circuit includes a voltage output section which outputs a voltage signal; a current source section and a conversion section. The current source section has at least one current source block comprising a plurality of current sources, each of which outputs an output current. The conversion section is provided between the voltage output section and the current source section and outputs a reference current to the plurality of current sources of the at least one current source block based on the voltage signal such that the output current from each of the plurality of current sources is set based on the reference current.
