Claim 12:
13. A method of reducing resistance-capacitance delay along photodiode transfer lines of an image sensor comprising:
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;
distributing selection transistors of a plurality of multiple-photodiode cells among the plurality of sublines;
providing a phase detection photodiode transfer line for each of a plurality of phase detection multiple-photodiode cell rows of the plurality of multiple-photodiode cells;
where there are three sublines of each of the plurality of photodiode transfer lines;
where the phase detection photodiode transfer line is unforked;
further comprising providing a plurality of standard rows comprising standard multiple-photodiode cells without phase-detection multiple-photodiode cells; and
providing a plurality of compensation rows of the multiple-photodiode cells.
