Abstract: A multi-phase generator according to an embodiment of the present invention includes an oscillator part including multiple first buffer parts which comprise a closed loop, and a delay part which includes multiple second buffer parts which are connected to multiple nodes between the first buffer parts, respectively. The phase of the output signal of the second buffer part connected to one among the nodes is further delayed compared to the phase of the output signal of the first buffer part receiving the signal of the node. A multi-phase generator according to the embodiment of the present invention can generate a signal having a desired phase by controlling a current supplied to a buffer.
