ABSTRACT:
In an embodiment, a circuit is provided comprising a multi-phase oscillator configured to output a plurality of output signals having the same frequency and different phase offsets. A feedback value is generated based on at least two of said output signals. A reference value is generated based on a reference clock and a predetermined value. The reference value and the feedback value are combined.
