SYSTEM AND METHOD FOR DELAYED CLOCK DISTRIBUTION IN COLUMN-PARALLEL A/D ARCHITECTURES USED IN CMOS IMAGE SENSORS

摘要

A system and method of distributing a clock is provided. The method comprises: receiving a clock signal; generating a complement of the clock signal; feeding both the received clock signal and the generated complement of the clock signal to a first of a plurality of latches connected in series; propagating the received clock signal and the generated complement of the clock signal through the plurality of latches connected in series; and tapping, at a plurality of locations along the plurality of latches, an output to drive a load, the output being either the clock signal as propagated or the complement of the clock signal as propagated.
