Apparatuses and methods for a level shifter with reduced shoot-through current

摘要

A level-shifting circuit with reduced shoot-through current includes an output circuit comprising high-voltage devices with a pull-up circuit configured for pulling up a voltage on an output signal to a high voltage responsive to a high-side control signal. The output circuit may also include a pull-down circuit configured for pulling down the voltage on the output signal to a low voltage in responsive to a low-side control signal. The level-shifting circuit can also include a high-side inverting buffer operably coupled between an edge-controlled signal and the high-side control signal, and a low-side buffer configured for driving the low-side control signal responsive to an input signal. The level-shifting circuit may also include an edge-control buffer operably coupled between the input signal and the high-side inverting buffer and configured to generate the edge-controlled signal with a slow rise time relative to a fall time.
