A multi-phase pulse generator provides an even number of pulse signals of same phase difference and pulse signals of higher frequency by applying a negative delay concept. The multi-phase pulse generator includes a first delay block with first unit blocks which have a first negative delay property respectively and of which an even number is ring-coupled; and a second delay block including second unit blocks which have a second negative delay property respectively and of which even number is ring-coupled. The number of the first unit block and the number of the second unit block are the same. A plurality of output nodes is formed based on one-to-one sharing between the first unit block and the second unit block having output signals of different level. Each output node outputs a pulse generated by racing the output signals of different level to each other which are provided from the first unit block and the second unit block connected to the each output node.
