Abstract
Dynamic voltage level shifting circuits, systems and methods are disclosed. A level shifting circuit comprises an input for accepting a first discrete voltage level to be shifted, a level shifting portion coupled to the input and to a second discrete voltage level, an enable portion having an enable input and coupled to the level shifting portion and an output. The level shifting circuit is configured to translate the data input at the first discrete voltage level into a second discrete voltage level. The enable portion is configured to selectively provide either the second discrete voltage level to the output or decouple at least a portion of the level shifting portion from the output based on the enable input.
