Moreover, recently, PLLs with an injection-locked frequency divider and frequency multiplier, and a clock and data recovery circuit (CDR) were presented. This paper describes a study on a ring-VCO-based PLL with pulse injection locking as a potential solution to realize a scalable inductorless ...
Generation of multi GHz and higher repetition-rate optical pulse trains directly from mode-locked oscillators is often challenging. As an alternative, harmonic injection locking can be applied for extra-cavity repetition-rate multiplication (RRM). Here we have investigated the operation conditions and ...
In a clock generating circuit having a plurality of injection-locking oscillators, a first one of the injection-locking oscillators is enabled to output a free-running reference clo
This paper presents a 20GHz subharmonic injection-locked clock multiplier (SILCM), which adopts a mixer based self-align injection timing control loop to guarantee the optimal injection point. In addition, to further improve the injection time accuracy and reduce the super, a V/I mismatch ...
