A multi-phase signal generator may include a duty control buffer configured to receive a first differential input signal and a second differential input signal, and generate a first differential output signal and a second differential output signal having variable duty ratios based on a control voltage, a first edge combiner configured to generate a first pulse signal based on first edges of the respective first and second differential output signals, a second edge combiner configured to generate a second pulse signal based on second edges of the respective first and second differential output signals, and a control voltage generator configured to generate the control voltage in response to a logic signal obtained by performing a logic operation on the first and second pulse signals.
