Abstract

Techniques are disclosed relating to feedback-controlled oscillators (e.g., phase-locked loops) arranged in two or more levels. In some embodiments, in a relatively higher-frequency mode, a first level feedback-controlled oscillator provides reference signals to one or more second level feedback-controlled oscillators that in turn generate output clock signals to clock sequential circuitry. In some embodiments, in a relatively lower-frequency mode, the first level feedback-controlled oscillator bypasses the second level feedback-controlled oscillators and provides output clock signals directly to sequential circuitry (without using any intervening feedback-controlled oscillators).
