Abstract
A spread-spectrum clock generator includes: a phase interpolator mixing a plurality of clock signals, which differ from each other in phase, and modulating a clock signal resulting from mixing the clock signals; and a controller generating a control signal to generate weights of the plurality of clock signals for modulating the clock signal. The phase interpolator regulates a modulation speed of the clock by adjusting a generation speed of the weights.
