Abstract
Provided is a current output circuit that includes: a first FET that has a power supply voltage supplied to a source thereof, that has a first voltage supplied to a gate thereof and that outputs a first current from a drain thereof; a second FET that has the power supply voltage supplied to a source thereof, that has the first voltage supplied to a gate thereof and that outputs an output current from a drain thereof; a first control circuit that controls the first voltage such that the first current comes to be at a target level; and a second control circuit that performs control such that a drain voltage of the first FET and a drain voltage of the second FET are made equal to each other.
