Systems and methods for generating an output oscillation signal with low jitter |
摘要 |
A circuit for generating an output oscillation signal with low jitter includes an oscillator to generate an oscillation signal at an initial frequency based upon a control input to vary an amplitude of the oscillation signal. A first frequency multiplier multiplies the oscillation signal to result in a first signal with first frequency and first undesired frequency components. A filter minimizes the first undesired frequency components of the first signal. A second frequency multiplier multiplies the first signal to result in the output oscillation signal with second frequency and second undesired frequency components. A second feedback circuit compares a predetermined range and at least one of the first signal and the output oscillation signal to result in a reference value. A first feedback circuit varies the control input based upon a comparison between the reference value and the amplitude of the oscillation signal to minimize the second undesired frequency components.
