Step 1 of 3 5.017P NMOS transistor is operated in Triode Region. Threshold voltage V₁ is 0.8 V Linear resistance is For is equal to 1.2 V it is found to have a resistance is 1000 Ω 1000 = 1 (1) For equal to 200 Ω gate source voltage applied is 200 = (2) Step 2 of 3 Divide equation (1) with (2) as follows: 1000 = 200 0.4 Thus, the gate source voltage is 2.8 V Step 3 of 3 Let R is the resistance of the device when width of the channel is doubled and is equal to 2.8 V R = (3) Divide equation (3) with (2) as follows: R = 200 1 2 Ω Thus, the value of resistance R is 100 Ω Ω
