摘要： A current driver outputs an output current according to a reference current. The current driver includes: a current-voltage converter; a bias-voltage generating transistor; a differential amplifier; and a driving transistor. The converter has a given resistance value and is connected between a first node and a second node. The bias-voltage generating transistor is provided between the first and second nodes and connected in series with the converter. The amplifier outputs a voltage according to the difference between a voltage at an interconnecting node between the converter and the bias-voltage generating transistor and a voltage according to the reference current at a third node. The driving transistor is connected between an output current node outputting an output current and the second node and receives, at its gate, the voltage from the amplifier. The bias-voltage generating transistor receives, at its gate, the voltage from the amplifier.
