ABSTRACT:
A circuit for removing noise from an input signal includes a falling edge signal delaying circuit configured to output a first delay output signal generated by delaying a falling edge of a first output signal for a preset time; a falling edge sensing circuit configured to sense the falling edge of the first output signal, and generate a pulse signal in accordance with the sense; a flip-flop configured to output the first delay output signal in accordance with an input clock signal; and a first logic operation circuit configured to perform a logic operation on an output signal of the flip-flop and the first output signal delayed for the preset time, thereby generating a second output signal.
