3. Design a common-source amplifier with a total power budget of 10 mW (the bias current should be 10% of the drain current) and a midband gain of 10, where VDD=5 V, VTH=0.6 V, H₂Cox 250 μA/V², Rig 50 , Rs 100 , and R₁= 500 2. (a) Determine the W/L ratio of the transistor and Rp in your design. Also, find R₁ and R₂ in your design. (b) Determine fi-3dB if Cc1= Cc2= 1 nF and Cs= 100 pF by hand calculation. (c) Determine fx-3dB if CGs=0.5 pF and CGD=0.3 pF by hand calculation.

![3. Design a common-source amplifier with a total power budget of 10 mW (the bias
current should be 10% of the drain current) and a midband gain of 10, where VDD=5
V, VTH=0.6 V, H₂Cox=250 μA/V², Rig 50 , Rs 100 , and R₁= 500 2.
(a) Determine the W/L ratio of the transistor and Rp in your design. Also, find R₁ and
R₂ in your design.
(b) Determine fi-3dB if Cc1= Cc2= 1 nF and Cs= 100 pF by hand calculation.
(c) Determine fH-3dB if CGS=0.5 pF and CGD= 0.3 pF by hand calculation.
(d) Verify and compare your results of the gain, f₁-3aB and fH-3dB by SPICE using
the .ac analysis to plot the transfer function (use the MOSFET large-signal model;
CGS and CGD can be added externally for simplicity, no need to be included in the
model).
