Abstract
A level shifting circuit can include a level shifting circuit input node that can be coupled to an input signal, where the input signal can be configured to switch between discrete voltage levels in an input voltage domain. A level shifting circuit output node of the level shifting circuit can be configured to provide shifted voltage levels that are shifted relative to the input signal responsive to switching of the input signal. A constant voltage element can have a first terminal that can be coupled to the level shifting circuit input node and can have a second terminal that can be coupled to the level shifting circuit output node. The constant voltage element can be configured to provide a constant voltage level shift to the input signal to provide the shifted voltage levels responsive to switching of the input signal between the discrete voltage levels in the first voltage domain.
