2-4 and 9-12 Gb/s CMOS fully integrated ILO-based CDR

100Gbit/s SiGe Clock and Data Recovery

“…The presented CDR uses an Injection Locked Oscillator (ILO) and a PLL as in [7] to ensure frequency tracking. An ILO can be approximated to a first order PLL [8], but with a limited locking range.…”

Windowed phase comparator for an 80Gbit/s CDR

“…The presented CDR uses an Injection Locked Oscillator (ILO) and a PLL as in [4] to ensure frequency tracking. An ILO can be approximated to a first order PLL [5], but with a limited locking range.…”

VHDL-AMS model of an injection locked VCO

“…When a signal is applied to an oscillator, the oscillator frequency will shift toward the applied signal frequency, under specific conditions. Injection locked oscillators are used in frequency-modulation receiver, in low phase noise frequency generation and in clock and data recovery [3][4].…”
