Abstract:
A noise detection circuit includes a first delay unit suitable for delaying a periodic wave to output a delayed periodic wave, a first divider unit suitable for dividing the delayed periodic wave to output a first periodic wave, a second divider unit suitable for dividing the periodic wave to output a divided periodic wave, a second delay unit suitable for delaying the divided periodic wave to output a second periodic wave, and a detection unit suitable for comparing the first periodic wave with the second periodic wave and outputting a noise detection signal.
