Q$2.$ Figure shows two NMOS transistors operating in saturation at equal $\backslash (\backslash$mathrm$\{$V$\}\_\{\backslash$mathrm$\{$GS$\}\}\backslash )$ and $\backslash (\backslash$mathrm$\{$V$\}\_\{\backslash$mathrm$\{$DS$\}\}\backslash ).$

a$.$ If the two devices are matched except for a maximum possible mismatch in their W$/$L ratios of $3\backslash \%($Q$2$ has $3\backslash \%$ more W$/$L than Q$1),$ what is the maximum resulting mismatch in the drain currents?

b$.$ If the two devices are matched except for a maximum possible mismatch in their Vt values of $10$ mV $,$ what is the maximum resulting mismatch in the drain currents? The nominal values of Vt for Q $1$ and Q $2$ are $0\mathrm{.}6$ V and $0\mathrm{.}61$ V $.$
