Abstract
A circuit can include an oscillator core that outputs, in response to a bias signal, a periodic signal having an oscillation frequency; a bias circuit that, when powered, provides the bias signal (e.g., a voltage) to the oscillator core; and a switching circuit that periodically powers the bias circuit at a second frequency and provides the bias signal to the oscillator core when the bias circuit is not powered. The switching circuit can include a storage element that stores energy when the bias circuit is powered and uses stored energy to provide the bias signal when the bias circuit is not powered. The switching circuit can include a divider circuit that divides the oscillation frequency of the periodic signal to generate a control signal having the second frequency, and the bias circuit can be periodically powered at the second frequency in response to the control signal.
