Abstract
Methods and apparatuses featuring a multiplying injection-locked oscillator are described. Some embodiments include a pulse-generator-and-injector and one or more injection-locked oscillators. The outputs of the pulse-generator-and-injector can be injected into corresponding injection points of an injection-locked oscillator. In embodiments that include multiple injection-locked oscillators, the outputs of each injection-locked oscillator can be injected into the corresponding injection points of the next injection-locked oscillator. Some embodiments reduce deterministic jitter by dynamically modifying the loop length of an injection-locked oscillator, and/or by using a duty cycle corrector, and/or by multiplexing/blending the outputs from multiple delay elements of an injection-locked oscillator.
