A time-to-digital system, such as a frequency synthesizer, includes a power management circuit and a time-to-digital converter (TDC). Said power management circuit is coupled to a frequency reference clock and a variable clock, and arranged to output a delayed frequency reference clock and a single pulse of said variable clock ahead of a transition of said delayed frequency reference clock. Said TDC is coupled to said power management circuit and arranged to produce a digital TDC output.
