Given a depletion-type MOSFET with IDSS = 6 mA and VP = −3 V, determine the drain current at VGS = −1, 0, 1, and 2 V. Compare the difference in current levels between −1 V and 0 V with the difference between 1 V and 2 V. In the positive VGS region, does the drain current increase at a significantly higher rate than for negative values? Does the ID curve become more and more vertical with increasing positive values of VGS? Is there a linear or a nonlinear relationship between ID and VGS ? Explain.
