Injection locking vco
Injection locking has been used in beneficial and clever ways in the design of early television sets and oscilloscopes, allowing the equipment to be synchronized to external signals at a relatively low cost. Injection locking has also been used in high performance frequency doubling circuits. Visa mer Injection locking and injection pulling are the frequency effects that can occur when a harmonic oscillator is disturbed by a second oscillator operating at a nearby frequency. When the coupling is strong enough and the … Visa mer Injection pulling and injection locking can be observed in numerous physical systems where pairs of oscillators are coupled together. Perhaps the first to document these effects was Christiaan Huygens, the inventor of the pendulum clock, … Visa mer High-speed logic signals and their harmonics are potential threats to an oscillator. The leakage of these and other high frequency signals into an oscillator through a substrate … Visa mer Entrainment has been used to refer to the process of mode locking of coupled driven oscillators, which is the process whereby two interacting Visa mer An injection-locked oscillator (ILO) is usually based on cross-coupled LC oscillator. It has been employed for frequency division or jitter reduction in PLL, with the input of pure sinusoidal waveform. It was employed in continuous mode clock and data recovery … Visa mer Injection locking can also provide a means of gain at a low power cost in certain applications. Visa mer Injection (aka frequency) pulling occurs when an interfering frequency source disturbs an oscillator but is unable to injection lock it. The … Visa mer Webb24 juni 2008 · The measured injection-locking range is 1422 MHz with 1.86-mW dc power consumption and 6-dBm input injection power. The injection-locking range of the proposed ILFT is similar to the tuning range of a conventional varactor-tuned bulk-CMOS voltage-controlled oscillator (VCO).

We revealed that comb generated by the gain-switched laser experiences a dramatic reduce of comb teeth linewidths in this regime. We demonstrated the Lorentzian linewidth of the comb teeth of sub-kHz scale as …
WebbAnother challenge is the slow locking time exhibited by conventional methods, which is undesirable for some applications. We propose a different approach, based on injection locking, that does not require an external reference clock, and thus can reduce the form factor of the overall transceiver.
