Patent attributes
A multi-phase clock generator for generating a set of multi-phase clock signals is disclosed. The multi-phase clock generator includes a signal generator, a phase adjusting circuit, and a phase interpolator. The signal generator generates a plurality of first clock signals according to a reference clock signal. The phase adjusting circuit, which is a phase rotator or a phase selecting circuit and coupled to the signal generator receives the first clock signals and adjusts the phases of the first clock signals according to a control signal to generate a plurality of second clock signals. The phase interpolator, which is coupled to the phase adjusting circuit, interpolates the second clock signals to generate the set of multi-phase clock signals.
