The present application is directed to a level shifting circuit. In one form, a level shifting circuit includes a first inverter, a level shifting unit, and a fast driving unit. The first inverter is configured to invert an input signal received at an input node and to output an inverted input signal to a second input node. The level shifting unit is configured to perform amplitude up-shifting processing on a received input signal. The fast driving unit is configured to pull up an output signal of an output node of the level shifting unit by increasing a discharge current of the level shifting unit when receiving the input signal.
