Abstract
Embodiments provide systems and methods for supporting reliable operation of crystals with widely varying fundamental modes of oscillation. In accordance with exemplary embodiments, an architecture is disclosed for an oscillator circuit which allows reliable operation for crystals varying over a wide frequency range, such as 12:1. Some embodiments use selectable current sources to provide variable range control for extending the range of frequencies over which the embodiments may operate properly. Other embodiments include symmetric topologies, cascode topologies, coupling elements, and/or other techniques to improve noise immunity and/or operation in low-source-voltage environments.
