Abstract
Embodiments of an oscillator and a method of operating an oscillator are disclosed. In an embodiment, an oscillator can include a ring oscillator core, a control circuit, and a timer that coordinates timing of the control circuit to avoid a current resulting from a voltage level associated with an output of the ring oscillator core during a startup and to allow the ring oscillator core to operate with a low startup current and a low operational power.
