D$5\mathrm{.}32$ For a particular n$-$channel MOS technology, in which the minimum channel length is $0\mathrm{.}2$ m$,$ the associated value of is $0\mathrm{.}5$ V$1.$ If a particular device for which L is $1\mathrm{.}0$ m operates in saturation at vDS $=1$ V with a drain current of $100$ A$,$ what does the drain current become if vDS is raised to $2$ V$?$ What percentage change does this represent? What can be done to reduce the percentage by a factor of $2?$
