摘要： 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.

摘要： Representative implementations of devices and techniques provide reduced jitter for a controlled oscillator. An edge of a reference signal is injected at various points within the oscillator, and is replaced for an edge of the generated oscillation signal at the injection point.

摘要： Methods and devices are discussed where a plurality of input signals having different phases are provided. From the input signals, a plurality of signal pairs are selected, and intermediate signals are generated based on the signal pairs. The intermediate signals are then combined.
