An NMOS transistor has parameters W = 10 µm, L=1 µm, k’ =194 µA/V2, λ = 0.024 V−1, tox = 80 Aͦ, ϕf = 0.3 V, Vt0 = 0.6 V, and NA = 5×1015 atoms/cm3. Ignore velocity saturation effects.

(a) Sketch the ID - VDS characteristics for VDS from 0 to 3V and VGS = 0.5 V, 1.5 V, and 3 V. Assume VSB = 0.

(b) Sketch the I- VGS characteristics for VDS = 2V as VGS varies from 0 to 2 V with VSB = 0, 0.5 V, and 1 V.
