Abstract
A voltage-current conversion circuit outputting a current corresponding to a difference between a first input voltage and a second input voltage, the voltage-current conversion circuit having a first current-mirror circuit supplied with the first input voltage as a power source and comprising at least one pair of transistors, a second current-mirror circuit supplied with the second input voltage as a power source and comprising at least one pair of transistors, a resistor connected between one of the pair of transistors of the first current-mirror circuit and one of the transistors of the second current-mirror circuit, and a third current-mirror circuit having a current source transistor supplying current to one of the pair of transistors of the first current-mirror circuit and another current source transistor supplying current to one of the pair of transistors of the second current-mirror circuit, a current output terminal being connected to one of the current source transistors.
