Sketch a set of iD-vDS characteristic curves for an NMOS Transistor operating with a small vDS. Let the MOSFET have k = 5ma/V^2 and Vt = 0.5V. Sketch and clearly label the graphs for VGS = 0.5,1.0,1.5,2.0, and 2.5V. Let VDS be in the range of 0 to 50mV. Give the value of rDS obtained for each of the five values of VGS. Although only a sketch your diagram should be drawn to scale as mush as possible.
