Abstract
Voltage level shifters employing preconditioning circuits are disclosed. Related systems and methods are also disclosed. In one aspect, voltage level shifter is configured to generate a voltage level shifted non-complement output signal and complement output signal corresponding to non-complement input signal and complement input signal, respectively. First pull-up circuit is configured to generate complement output signal in response to non-complement input signal transitioning to logic low voltage. First pull-down circuit is configured to generate non-complement output signal in response to complement input signal transitioning to logic high voltage. First preconditioning circuit is configured to receive non-complement and complement output signals and generate and provide shifted voltage signal to complement output in response to non-complement output signal transitioning to logic low voltage. This allows the complement output signal to transition to the shifted voltage more quickly.
