Engineering

A MOSFET current gain amplifier is shown in Figure (a).

The transistor parameters are K_n= K_p = 10 mA/V², V_TN = 1 V, V_TP = -1 V, and λ_n = λ_p = 0. The LED turn-on voltage is V_γ = 1.6 V.

Assume the LED small-signal resistance is r_f = 0.

(a) Determine the quiescent currents I_DQ1 and I_DQ2.

(b) Determine the small-signal current gain A_i = I_o/I_i .
