Abstract:
A reference current output device and reference current output method that may adjust a reference current while maintaining a temperature gradient. In the reference current output device and reference current output method of the present invention, a reference current is outputted by a reference voltage and current output circuit, a reference voltage outputted from the reference voltage and current output circuit is converted to an adjustment current and outputted by a conversion and output circuit, the adjustment current is superimposed with the reference current and a superimposed current is outputted by a superimposition and output section.
