Abstract In this paper, an automated system for oscillator phase noise measurement is described. The system is primarily intended for use in academic institutions, such as smaller university or research laboratories, as it deploys standard spectrum analyzer and free software. A method to compensate the effect of instrument intrinsic noise is proposed. Through series of experimental tests, good performances of our system are verified and compliance to theoretical expectations is demonstrated.

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
