3. Figure Q3 shows the \( i-v \) characteristics curve of a \( \mathrm{n} \)-channel MOSFET (NMOS). Which of the following statement(s) regarding NMOS are true? (There can be multiple answers.) (4 marks) (a) An NMOS biased in the saturation mode operates in region II. (b) The \( Q \)-point of an NMOS small-signal amplifier should lie in the saturation region. (c) An inversion layer of electrons is induced in the channel region when the gate-to-source voltage of an NMOS is smaller than the threshold voltage \( \left(v_{\mathrm{GS}}
