INTEGRATED CIRCUIT HAVING A MULTIPLYING INJECTION-LOCKED OSCILLATOR

摘要

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.
