    Area Estimation NAND3

    For a rough area estimation Focus on the number of metal lines (assuming all are contacted)

    8 between any such two metal-1 lines

    NAND3 With all capacitances

    Figure shown, considers all diffusion capacitances

    However, based on the layout, the diffusion capacitances mayreduce, due to source-drain sharing/merging (see next slide)
