The parameters of the basic source-follower circuit in given Figure are RS = 1.5 k Ω, VT N = 1.2 V, and λ = 0. Assume the transistor is biased at IDQ = 1.2 mA.

(a) If the transistor conduction parameter is Kn = 1.5 mA/V2, determine

(i) Av f = vo/vi and

(ii) Rof .

(b) If the conduction parameter increases by 50 percent to Kn = 2.25 mA/V2, determine the percent change in (i) Avf = vo/vi and (ii) Rof .
