$14\mathrm{.}19$ For the technology specified in Problem $14\mathrm{.}26,$ investigate the variation of $V_M$ with the ratio $\frac{W_p}{W_n}.$ Specifically, calculate $V_M$ for $($a$)W_p=3\mathrm{.}5W_n($the matched case$)$; $($b$)W_p=W_n($the minimum$-$size case$)$; and $($c$)W_p=2W_n($a compromise case$).$ For cases $($b$)$ and $($c$),$ estimate the approximate reduction in $N{M}_L$ and silicon area relative to the matched case $($a$).$
