Abstract
A multimode, multicore inductor-capacitor (LC) oscillator having an increased oscillation frequency tuning range, and related method, are provided. The oscillation frequency tuning range of existing oscillators is limited. LC oscillators are known to have very low phase noise but a narrow frequency tuning range. The present oscillator has at least two LC oscillator cores and is capable of operating in multiple different modes of oscillation thereby increasing its overall oscillation frequency tuning range. A set of programmable amplifier pairs is used to force particular relative oscillation phases at the nodes of the multiple cores of the oscillator to realize one or more additional modes of oscillation for the oscillator. The additional oscillation mode increases the frequency tuning range of the oscillator.
