Abstract (en)
[origin: EP0872789A2] An internal supply voltage (Vccint) generation circuit arrangement including a reference voltage generator (RG) which detects a voltage proportional to the external supply voltage (Vccext) and then generates a reference voltage (Vref) in dependence of the amplitude of this voltage, the reference voltage serving to control the internal supply voltage (Vccint) generating device. At least two constant voltage values of the reference voltage (Vref) can be generated from the reference voltage generator (RG), the latter comprising at least two voltage sources (VREF1,VREF2), one of which is designed with a double current-mirror circuit.
