ABSTRACT:
A substrate voltage generating circuit including level shifting circuits, a first power supply node of a first potential level VDDa second power supply node of a second potential level VSSlower than the first potential level, and an output node OUT.vbb having a third potential level VBBlower than the second potential level. The level shifting circuits are coupled between the first power supply node and the output node, receiving an input signal having the first and second potential levels, and outputting an output signal VBBhaving the first potential level and the third potential level. The substrate voltage generating circuit also includes a switch circuit connecting the second power supply node to the output node in response to the output signal VBB
