In this paper, ring oscillator phase noise caused by power supply noise (PSN) with deterministic frequency is analyzed. Results show that phase noise caused by deterministic noise is only an impulse series. Compared with the jitter caused by PSN, the phase noise caused by PSN with deterministic frequency contributes considerably less to total phase noise performance. To verify the analysis method, a CMOS ring oscillator is designed and fabricated using SMIC 0.13 µm CMOS process. Comparisons between the analytical results and measurements prove the accuracy of the proposed method

An optoelectronic oscillator (OEO) is an optoelectronic hybrid oscillator which utilizes ultra-low loss fiber as an electro-magnetic energy storage element, overcoming the limits of traditional microwave oscillators in phase noise performance. Due to their ability to generate ultra-low phase noise microwave signal, optoelectronic oscillators have attracted considerable attentions and are becoming one of the most promising and powerful microwave signal sources. In this paper, we briefly introduce the operation principle and discuss current research on frequency stability and spurious suppression of optoelectronic oscillators.
