Calculate the total equivalent input noise current for the shunt-shunt feedback circuit of Fig. 8.48 in a bandwidth from 0.01 Hz to 100 kHz. Use the MOS transistor data in Problem 11.5. Ignore gate-current noise in (11.15) and (11.16).

Data from Prob. 11.5:

Calculate the total input- and output-referred noise voltages at 10 Hz, 100 kHz, and 1 GHz for the common-source amplifier shown in Fig. 7.2b. Assume that W=100 µm,L=1 µm,I_D=100 µA,V_t =0.6V,k€™ =194 µA/V²,t_ox =80 Ǻ,L_d =0,X_d =0,andK_f =3×10^ˆ’24F-V². Ignore gate-current noisein (11.15) and (11.16). Let RS =100 kΩandR_L=10 kΩ. Verify your result using SPICE. (Add dcsources for SPICE.)
