In the test circuit of let VSB 5 0 and VDS 5 2 V, and let vGS be variable from 0 to 5 V. (a) Assuming Vt 5 1.0 V, k 5 1 mA/V2 , and 5 0, sketch and label the plot of iD versus vGS. Hint: as vGS is varied from 0 to 5 V, MOSFET operation goes from cutoff, to saturation, to triode. (b) Find the device’s dynamic resistance r at vGS 5 2 V and at vGS 5 4 V. (Recall that r is the reciprocal of the slope.)
