WebbThe DFC first employs a subharmonic injection-locked ring oscillator (ILRO) to generate low phase noise, high-frequency fixed reference from a crystal oscillator (XO). $\Delta \Sigma $ modulator ( $\Delta \Sigma \text{M}$ …
WebbThe proposed system uses the power-efficient injection-locking ring oscillator (ILRO) to replace the LC oscillator which occupies much more area on chip with higher power consumption. In addition, through the ILRO, the frequency modulated input signal is converted to a full swing rectangular signal, which can be directly demodulated by a … WebbIn this paper, we introduce a unified nonlinear injection locking model of a large class of 1:2 frequency dividers. The model is valid for two-stage dividers, injected with two-phase or single-phase current or voltage sources. We show that this class of dividers can be rigorously analyzed using the theory of planar nonlinear dynamical systems.
Webbphase-locked loop (PLL), is a promising solution for the design of high-performanceclockmultipliers and frequencysynthe- sizers [1]–[4]. In fact, the superior suppression of the oscillator phase noise provided by the injection-locking mechanism com-pared to thatprovidedby the PLL allowsone to get frequency
Webban injection source and the oscillator are separated: one is an injector, and the other is an injectee; mutual injection is found only rarely, thereby out of concern in this paper.
