Abstract
In this paper, a new Figure of Merit (FoM) of LC oscilators considering frequency tuning range is proposed. The oscillators which have wide frequency tuning range are demanded due to the recent wireless technology. FoM is often utilized to evaluate oscillators. However, the conventional FoM does not consider the frequency tuning range, which degrades the phase noise drastically. The proposed FoML can consider the degradation caused by wide frequency tuning range, which is derived from degradation in quality factor of inductor. The simulation results are presented with the analytical explanation, and these FoMs are compared using the results in reference papers.
