OX 5.5. (a) Consider a device with µCox = 500 µA/V², α = 1.1, &. = 2.5 × 104 V/cm, and V₁=0.4 V. By using the model of Example 5.1, plot

Ips VS. Vps for Vps up to 1.2 V, with VGS as a parameter (VGs = 0.6, 0.9, 1.2 V), and for W = L = 0.8, 0.4, and 0.2 µm. (b) Repeat for the preceding values of L, but keep W constant at 0.8 µm. Discuss the results obtained. Neglect the effect of channel length and width on the threshold voltage.
