Problem 1: An n-channel enhancement-mode MOSFET with parameters VTR = 2 V and K = 1 mA/V2 is connected to the circuit below with VDD = 10 V and RD = 1 kΩ. (a) Plot the v−i characteristics of the MOSFET for VTR < VGS < 8 and 0 ≤ VDS ≤ 10 V. (b) Draw the load line imposed by VDD and RD over this set of v−I characteristics. (c) Graphically determine the transfer characteristic of the inverter over the range 0 < vIN < 8 V.
