Question 9

Essay

The MOSFET in the common-source amplifier in Fig. 10.9.1
 The MOSFET in the common-source amplifier in Fig. 10.9.1      Figure 10.9.1  is operating at  g_{m}=5 \mathrm{~mA} / \mathrm{V}  and has  C_{g s}=1 \mathrm{pF}  and  C_{g d}=0.2 \mathrm{pF} . Channel-length modulation is negligibly small. (a) Find the midband voltge gain in  \mathrm{dB} . (b) Find the upper 3-dB frequency,  f_{H} . (c) Find the value of  C_{G}  that places the pole it introduces at  1 \mathrm{~Hz} . (d) Find the value of  C_{S}  that places the pole it introduces at  100 \mathrm{~Hz}  (e) Find the value of  C_{D}  that places the pole it introduces at  10 \mathrm{~Hz} . (f) Sketch and carefully label the Bode plot for the gain magnitude. Specify the lower 3-dB frequency,  f_{L} .
