WebbFigure 1 shows an injection-locked PLL (ILPLL). The PLL is based on a ring VCO that is able to generate high-frequency outputs across wide frequency range, as well as … Webb26 feb. 2015 · Ring-based injection-locked oscillators (ILO) can also be used to generate quadrature phases from a reference clock without frequency division, which is desirable for half-rate and quarter-rate CDR. However, ILO inherently has a small locking range making it less suitable for wideband applications. population of kingsbridge devon
