D $6\mathrm{.}84$ Consider the classical biasing scheme shown in Fig. $6\mathrm{.}48($c$),$ using a $9-$V supply. For the MOSFET, $V_1=1V,=0,$ and $k_n=2m\frac{A}{V^2}.$ Arrange that the drain current is $1$ mA $,$ with about one$-$third of the supply voltage across each of $R_S$ and $R_D.$ Use $22M$ for the larger of $R_{G1}$ and $R_{G2}.$ What are the values of $R_{G1},R_{G2},R_s,$ and $R_D$ that you have chosen? Specify them to two significant digits. For your design, how far is the drain voltage from the edge of saturation?
