Q 3. The depletion NMOS amplifier of Figure 2 has

R_{s} = 500 Ω, R_{L} = 10 k Ω, R_{S R} = R_{D} = 5 k Ω

,

R_{G} = 100 k Ω, I_{D D} = 10 m A, V_{p} = - 4 V, | V_{M} | = 200 V

, and

V_{D D} = 12 V

. Calculate (a) the input resistance

R_{in} = v_{s} / i_{s}

, (b) the no-load voltage gain

A_{v o} = v_{o} / v_{g}

, (c) the output resistance

R_{o}

, and (d) the overall voltage gain

A_{v} = v_{L} / v_{s}

.
