If one end of the resistor in problem $2\mathrm{.}10$ is tied to $+1$ V and the other end is tied to the substrate that is tied to ground, estimate the depletion capacitance $($F$/$m$^2)$ between the n$-$well and the substrate at the beginning, the middle, and the end of the resistor. Assume that the resistance does not vary with position along the resistor and that the scale factor is $50$ nm$,$ Co $=25$ af for a $10$ by $10$ square, m$=0\mathrm{.}5,$ and Vi$=1$
