ABSTRACT:
Methods and apparatus for distributing clock signals to an integrated circuit provide for: producing, in a slow mode of operation, a first clock signal having at least first and second on-pulses of differing first and second on-times each period, respectively, where a sum of the first and second on-times is approximately equal to a sum of off-times each period; distributing the first clock signal through a distribution tree and terminating at a plurality of final buffer circuits that produce respective distributed clock signals from which respective second clock signals are produced to supply at least a portion of the integrated circuit; deleting the second on-pulse from each of the distributed clock signals each period to produce the respective second clock signals, the second clock signals each including at least a portion of the first on-pulse, but none of the second on-pulse each period.
