The output curves of an $n$-channel enhancement-mode MOSFET are shown in Figure P11.29. This transistor is placed in the common source amplifier in Figure P11.28 with $R_1=100 \mathrm{k} \Omega, R_2=30 \mathrm{k} \Omega$, and $R_D=$ $1.25 \mathrm{k} \Omega$. (a) Construct the load line for this circuit. (b) Obtain the quiescent operating point, that is, $Q$-point. (c) If $v_i$ is a sinusoidal signal of amplitude $1 \mathrm{~V}$,sketch the variation of the output voltage $v_o$ about the operating point. (d) Find the large-signal voltage gain. (e) Describe any possible distortion of the output signal. If we reduce the amplitude of the input signal, would there be less distortion?
