Question:

(a) At what frequency are the noise spectral densities, i̅²_g /∆f, for the gate-current noise in (11.15) and (11.16) equal? Assume that W = 50 µm, L = 0.5 µm, I_G= 0.05 fA, I_D= 100 µA, V_t = 0.6 V, K’ = 194 µA/V², t_ox = 80 Ǻ, L_d = 0, X_d = 0, and K_f = 3 × 10⁻²⁴ F-V².

(b) For this transistor, considering only the gate-current noise, in what bandwidth (from 0 to f_BW) are the total input noise currents due to shot noise in (11.15) and coupled thermal noise in (11.16) equal?
