摘要:
A current driving circuit includes: a reference input terminal to which a first reference current is given; a current mirror circuit for receiving the first reference current and outputting a first internal current corresponding to the first reference current; a bias voltage generation section for receiving the first internal current and generating a bias voltage corresponding to the first internal current; an output reference current generation section for receiving the bias voltage and generating a second reference current corresponding to the bias voltage; a reference current output terminal for outputting the second reference current; an internal current generation transistor for receiving at a gate thereof the bias voltage and generating a second internal current corresponding to the bias voltage; and an output current generation section for receiving the second internal current and generating n output currents corresponding to the second internal current.
