(a) The test circuit is adjusted so that VSG 5 VBS 5 0. Given that ID 5 240 A for VSD 5 8 V, ID 5 210 A for VSD 5 2 V, and ID 5 150 A for VSD 5 0.5 V, and given that ID drops to zero if VBS is raised to 6 V, identify the device type (enhancement or depletion?) and fi nd Vt 0, k, , and . Assume n 5 0.35 V. (b) Predict ID with VSG 5 VBS 5 VSD 5 2 V.
