The MOSFET amplifier circuit shown below has RF=3 M2, RG=2 M22, Ibias= 200 °A, Vt=0.5 V, kin= 1 mA/V?, W/L=2, VA= 20 V a) Sketch the dc equivalent circuit and Label node voltages and branch currents b) Assuning a=0 and neglecting the current in the feedback network, find VGS c) Find VDS and the current in the feedback network (I). Was the assumption of neglecting 1–0 in part (b) justified? Verify. d) Sketch the complete small-signal equivalent circuit e) Neglecting the current in RF (3MS2), find the voltage gain Av = vo/vi f) Find the maximum possible sinewave signal peak at the output while the NMOS remains in saturation, then deduce the corresponding signal peak vi g) Sketch the waveform of Vps vs time (total volatge at the drain) 200 μΑ 3 M2 OVO 00 vi 2 ΜΩ Rin Page 7 1 8 - a + =
