Abstract
An embedded system includes a level shifter circuit for generating a forward supply voltage level in a predefined range. A sense circuit senses a core supply voltage level of the embedded system and compares the sensed core supply voltage level with a predetermined minimum core supply voltage level needed to generate the forward supply voltage. A reset circuit maintains one or more input nodes and one or more internal nodes of the level shifter circuit at a predetermined voltage level when the core supply voltage level is less than the predetermined minimum core supply voltage level.
