Abstract
A clock generator includes an oscillator configured to generate an oscillating signal and a signal path configured to provide an output clock signal based on the oscillating signal. In response to a control signal, the clock generator is configured to neutralize periodic phase perturbations in the oscillating signal using opposing periodic phase perturbations. The neutralization may occur in the signal path. The signal path may be responsive to the control signal to adjust at least one of a duty cycle, a rise time, and a fall time of the output clock signal to cause alternating phase perturbations of the periodic phase perturbations to apply as the opposing periodic phase perturbations in the output clock signal. The neutralization may occur in the oscillator. The clock generator may include an auxiliary path configured to provide an auxiliary signal to the oscillator.
