Abstract
A current to be supplied to a load driven by the current is linearly controlled in accordance with a voltage. A voltage-current converter according to the present invention includes a differential amplifier, a first current mirror, and a voltage setting unit. The differential amplifier receives an input voltage from an input terminal and outputs a voltage in accordance with a difference between the input voltage and a threshold voltage. The first current mirror receives the voltage from the differential amplifier and outputs an output current to an output terminal. The voltage setting unit sets the threshold voltage.
