Abstract
A level shifting circuit and method that reduce leakage current are provided. The level shifting circuit includes: a logic circuit including a plurality of MOSFETs (metal-oxide-semiconductor field effect transistors) connected in series between an output terminal and a source, receiving an input signal having a first logic level and a second logic level, changing the input signal to a signal having a first logic level and a third logic level in response to a feedback signal supplied to one of the MOSFETs, and outputting the changed signal as an output signal; and a feedback circuit generating the feedback signal in response to the output signal.
