ABSTRACT:
A voltage generator circuit includes a storage capacitor with a terminal for pickup of an output voltage. A voltage generator device which can be turned on and off has an output being connected to the terminal of the storage capacitor. A first comparator device which can be turned on and off compares the output voltage with a first threshold voltage and generates a signal for turning the voltage generator device on and off. A second comparator device compares the output voltage with a second threshold voltage and generates an output signal with which the first comparator device is turned on and off.
