An integrated electronic device for generating a reference voltage. The circuitry has a bias current generator for generating a first bias current, a diode element coupled to the bias current generator and fed by a second bias current derived from the first bias current for converting the second bias current into a reference voltage across the diode element, a supply voltage pre-regulator stage for regulating the supply voltage used for the bias current generator, and an output buffer coupled to the reference voltage for providing a low impedance output, wherein the reference voltage is coupled to the supply pre-regulator stage for biasing the supply pre-regulator stage by the reference voltage.
