An injection-locked ring oscillator-based phase-locked-loop targeting clock recovery for space application at 3.2 GHz is presented here. Most circuits need a very low phase noise and jitter performance are thus based on LC-type oscillators. These excellent performances come the expense of poor integration density. To alleviate this issue, work introduces an PLL circuit. The combination injectio...

Injection locking can stabilize a source of radiation, leading to an efficient suppression noise-induced spectral broadening and therefore, narrow spectrum. The technique is well established in laser physics, where phenomenological description due Adler usually sufficient. Recently, experiments were performed Josephson photonics devices, microwave radiation created by inelastic Cooper pair tunn...

This article presents a millimeter-wave (mmW) frequency synthesizer based on new charge-sharing locking (CSL) technique. A charge-preset capacitor is introduced for charge sharing with resonant LC -tank phase correction, while the resulting residue processed by digital frequency-tracking loop (...

Theory and experiments on the side-mode-suppression-ratio (SMSR) enhancement and the linewidth reduction of a Fabry-Perot laser diode (FPLD) side-mode-injection-locked by using another FPLD are demonstrated to realize its potential application as a DWDM transmitter source. The SMSR, the spectral linewidth and the linewidth enhancement factor are simulated to realize the limitation of the FPLD-F...

Directly modulated fiber-optic links generally suffer higher link loss and larger signal distortion than externally modulated links. These result from the electron-photon conversion loss and laser modulation dynamics. As a method to overcome the drawbacks, we have experimentally demonstrated the RF performance of directly modulated, ultra-strong injection-locked gain-lever distributed Bragg ref...

In this paper, a 30 GHz wide locking-range (26.2 GHz-35.7 GHz) direct injection-locked frequency divider (ILFD), which operating in the millimeter-wave (MMW) band, is presented. The locking range of the ILFD is extended by using differential injection topology. Besides, varactors are used in RLC resonant tank for extending the frequency tuning range. The post simulation results show that a wide...
