P $6.$ Design $-$ The FET in the circuit has Vt $=1$ V$,$ kn $=0\mathrm{.}5$ mA$/$V$2.$ Given that VDS $=6$ V and VS $=4$ V$,$ it is desired to have a bias current equal to $0\mathrm{.}1$ mA$.$ Determine the values for the following parameters: a$)$ Gate voltage VG b$)$ resistors RG$1$ and RG$2$ c$)$ Drain voltage VD and resistance RD
