1. The problem statement, all variables and given/known data A MOSFET has the set of v-I characteristics shown in Fig. P5.5. What are the values of K and VTR? 2. Relevant equations iD=K(VGS-VTR)2 3. The attempt at a solution I have looked in the book and all of the example problems give VTR, but it doesn't show how to actually get the K and VTR values based on the graph. I really have no idea what to do. The answer in the book says K=0.25 mA/V2 and VTR=2V. Is VTR 2V because VGS increases by 2V?
