5.68 For a particular depletion-mode NMOS device, Vt = −2 V, W/L = 200 μA/V2, and λ = 0.02 V. When operated at vGS = 0, what is the drain current that flows for vDS = 1V, 2 V, 3 V, and 10 V? What does each of these currents become if the device width is doubled with L the same? With L also doubled? 0.3 mA, 0.416 mA, 0.424 mA, 0.48 mA; each current value is doubled; for vDS = 2V, iD = 0.408 mA; for vDS = 3 V, iD = 0.412 mA; for vDS = 10 V, iD = 0.44 mA
