In the circuit of Fig. P3.21 let R 5 1 kV and let the FET have Vt 5 1.0 V and k 5 2 mA/V2 . Assuming 5 0, sketch and label the i-v characteristic for 0 # v # 5 V. Calculate it at a few signifi cant points, and use physical insight to predict the ultimate slope of this characteristic for large values of v. Hint: as v is raised from 0 V, the FET operates fi rst in cutoff, then in saturation, and fi nally in the triode region.
