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, and K_f= 3 × 10^ˆ’24F-V². Ignore gate-current noise in (11.15) and (11.16). Let RS =100 kΩ and R_L= 10 kΩ. Verify your result using SPICE. (Add dc sources for SPICE.)
