ABSTRACT:
A clock generator generates multiple clock signals based on an input signal and adjusts the phases of the clock signals relative to a phase of the input signal, based on a control signal. The clock generator includes a phase locked loop that includes a phase shift unit. The phase shift unit selects some of the clock signals based on the control signal and generates a feedback signal based on the selected clock signals. The feedback signal has a phase based on the phases of the selected clock signals. The phase locked loop aligns the phase of the feedback signal with the phase of the input signal. In this process, the phase locked loop shifts the phase of each of the clock signals relative to the phase of the input signal.
