Consider the NMOS inverter with depletion load in Figure(b).
The transistor parameters are VTNDO = 0.4 V, VTNLO= -0.6 V, K D = 100μA/V2, KL = 20μA/V2, γ = 0.25 V1/2, and φfp = 0.35 V.
Determine vI when vO = 1.25 V for the case when (a) the body effect is neglected and (b) the body effect is taken into account.
