  • Voltage generator with standby operating mode
    Patent number: 6570367
    Abstract: A voltage generator for producing an internal supply voltage has a standby voltage generator and a voltage generator for normal operation that are controlled in common by a reference voltage. In addition, a comparator stage is provided whose switching threshold is set lower than the reference voltage by using a voltage divider that is connected to the reference voltage. The additional comparator stage thus activates the voltage generator for normal operation when the internally produced voltage falls below its switching threshold so that the internal supply voltage is stabilized.
    Type: Grant

    Date of Patent: May 27, 2003
    Assignee: Infineon Technologies AG
