Abstract:
Techniques are disclosed relating to rapidly downshifting the output frequency of an oscillator. In some embodiments, the oscillator is configured to operate in a closed-loop mode in which negative feedback is used to maintain a particular output frequency (e.g., in a phase-locked loop (PLL)). In some embodiments, the negative feedback loop is configured to maintain the output of the oscillator at a particular frequency based on a reference clock signal and the output of the oscillator. The nature of a negative feedback loop may render rapid frequency changes difficult, e.g., because of corrections by the loop. Therefore, in some embodiments, the loop is configured to switch to an open-loop mode in which a control input to the oscillator is fixed. In some embodiments, the loop switches to open-loop mode in response to a trigger signal and control circuitry forces the oscillator to a new target frequency.

Claim (Index 9):
A method, comprising:\n operating an oscillator and feedback circuitry in a closed-loop mode in which the feedback circuitry varies one or more control signals based on both the output of the oscillator and a reference signal to cause the oscillator to generate an output clock signal at a first frequency; in response to a trigger signal from sensor circuitry, operating the oscillator in an open-loop mode of operation in which the oscillator generates the output clock signal at a second frequency that is lower than the first frequency, without feedback based on output of the oscillator; and processing instructions in both the closed-loop mode and the open-loop mode using circuitry that is clocked by the output clock signal.
