Abstract
Disclosed is a receiving circuit, which includes a hysteresis detector that receives an input signal corresponding to a first voltage level and outputs a detection signal having a first threshold voltage and a second threshold voltage, and a level shifter that receives the detection signal, converts the first voltage level of the detection signal to a second voltage level higher than the first voltage level so as to be output as an output signal, and outputs a feedback signal of the second voltage level, and the hysteresis detector receives the feedback signal from the level shifter and adjusts the first threshold voltage and the second threshold voltage based on the feedback signal.
