For vxnbsp 5 v output vo1nbspis 015 v and the power

Question

The transistor parameters for the circuit in Figure are: V_T N = 0.8 V for all enhancement-mode devices, V_T N = -2 V for the depletion-mode devices, and  = 60 μA/V² for all devices. The width-to-length ratios of M_L2 and M_L3 are 1, and those for M_D2, M_D3, and M_D4 are 8.

(a) For v_X = 5 V, output v_O1 is 0.15 V, and the power dissipation in this inverter is to be no more than 250 μW. Determine (W/L)_{M L1} and (W/L)_{M D1}.

(b) For v_X = v_Y = 0, determine v_O2.
