Abstract
A current-generator circuit is for generation of an output current of a value that is configurable as a function of a configuration signal. The circuit may have a first reference resistor element traversed by an intermediate current, the value of which is a function of a reference current, for supplying a first reference voltage. The circuit may also include a resistive divider stage receiving the configuration signal and supplying a second reference voltage as a function of the first reference voltage and of the configuration signal. A second reference resistor element supplies, as a function of the second reference voltage (V), the output current on the output terminal. The value of resistance of the second reference resistor element may be matched to a respective value of resistance of the first reference resistor element.
