The small-signal parameters of an enhancement-mode MOSFET source follower are (g_{m}=5 mathrm{~mA} / mathrm{V}) and (r_{o}=100 mathrm{k}

Question:

The small-signal parameters of an enhancement-mode MOSFET source follower are \(g_{m}=5 \mathrm{~mA} / \mathrm{V}\) and \(r_{o}=100 \mathrm{k} \Omega\).

(a) Determine the no-load small-signal voltage gain and the output resistance.

(b) Find the smallsignal voltage gain when a load resistance \(R_{S}=5 \mathrm{k} \Omega\) is connected.
