Figure shows an amplifier constructed from a field-effect transistor with mutual conductance g m = 2 ?

Question:

Figure shows an amplifier constructed from a field-effect transistor with mutual conductance g_m = 2 ? 10^-3 S.

For small a.c. signals v_in calculate:

(i) The voltage gain of the amplifier;

(ii) The input impedance.

(The capacitors C₁ and C₂ can be assumed to have negligible a.c. impedances.)
