Abstract: In an embodiment, a method of reducing resistance-capacitance delay along photodiode transfer lines of an image sensor includes forking a plurality of photodiode transfer lines each into a plurality of sublines coupled together and to a first decoder-driver at a first end of each subline; and distributing selection transistors of a plurality of multiple-photodiode cells among the plurality of sublines. In embodiments, the sublines may be recombined at a second end of the sublines and driven by a second decoder-driver at the second end.
