A clock circuit includes an oscillator having a biasing node that causes the oscillator to enter a low-power state. The clock circuit also includes a kick-start circuit and a first mechanism. The kick-start circuit operates to provide an excitation to the oscillator, where the excitation enables the oscillator to start its oscillation. The first mechanism is configured to inhibit kick-start based on certain conditions, such as when the oscillator reaches a particular level capable of sustaining oscillation by itself or when the oscillator is already running.
