Claim 23:
24. The method of claim 21, wherein:
the ring oscillator comprises a set of N cascaded inverters arranged to form a ring, wherein N is a positive integer number;
the at least one second upper voltage rail comprises a set of N/2 upper voltage rails;
the at least one second lower voltage rail comprises a set of N/2 lower voltage rails;
supplying current from the first upper voltage rail to the ring oscillator comprises supplying a first set of currents from the first upper voltage rail to pairs of the set of N cascaded inverters via the set of N/2 upper voltage rails based on a data phase alignment signal, respectively; and
sinking current from the ring oscillator to the first lower supply voltage rail comprises sinking a second set of currents from the pairs of the set of N cascaded inverters to the first lower supply voltage rail via the set of N/2 lower voltage rails based on the data phase alignment signal, respectively.
