Abstract
Representative implementations of devices and techniques provide reduced jitter and local phase detection for a controlled oscillator. An edge of a reference signal is injected at a point within the oscillator, and replaces an edge of the generated oscillation signal at the injection point. A phase difference of the injected reference signal and the oscillation signal is measured locally and is used to tune the oscillator.
