(a) In the test circuit of let VGS 5 0 and VSB 5 0. If it is found that ID 5 112 A at VDS 5 3 V, and ID 5 120 A at VDS 5 5 V, identify the device type (enhancement or depletion?) and fi nd . (b) Now let VGS 5 1.5 V and VDS 5 5 V. If it is found that ID 5 750 A with VSB 5 0, and ID 5 480 A with VSB 5 2 V, fi nd k, Vt0, and , assuming p 5 20.35 V. (c) Predict ID if VGS 5 0, VSB 5 5.3 V, and VDS 5 1 V, and comment on your fi ndings. (d) Repeat part (c) if VGS is raised to 2 V.
