Abstract: A multi-phase generator includes an oscillator unit including a plurality of first buffer units forming a single closed loop and a delay unit including a plurality of second buffer units respectively connected to a plurality of nodes, wherein each of the plurality of nodes is connected between two adjacent buffer units of the first buffer units. A phase of an output signal of a second buffer unit, among the second buffer units, lags behind a phase of an output signal of a first buffer unit, among the first buffer units.
