Internal supply voltage generating device, has switch on voltage generating part for generating switch on voltage, where voltage generating part is switched off by reference voltage, which is generated by reference voltage generating part

摘要

The device has a switch on voltage generating part (40) for generating a switch on voltage (VDD-SU) using an external supply voltage (VDD-EXT). A reference voltage generating part (41) generates a reference voltage (VREF) using the switch on voltage. A generating part (42) generates an internal supply voltage (VDD-INT) using the reference voltage and external supply voltage. The switch on voltage generating part is switched off by the reference voltage, which is generated by the reference voltage generating part. An independent claim is also included for a method for generating an internal supply voltage.
