You are given that VTH = 1 V, VGS = 3 V, VDD = 18 V, and RD = 225 Ω. Use the ID−VDS characteristics to find the transistor parameter k and the value of ID that results when operating at VDS = 9 V. Note: You may want to use equations for improved accuracy. ID = number (rtol = 0.01, atol = 1 e−05) mA
