Problem $2(6$ pts$)$ In the circuit to the right, the OpAmp is ideal. The NMOS device has K $=210-3$ A$/$V$2.$ And VT $=1$V$.$ Treat the NMOS with SCS model. $(1)(3$ pts$)$ If VI $=1$V$,$ VA $=1\mathrm{.}5$v$.$ Find vo$.$ Justify any assumptions about the state of M$.(2)(3$ pts$)$ If VI $=2$V$,$ VA $=5$v$.$ Find vo$.$ Justify any assumptions about the state of M$.$
