Step of 9 5.023P Threshold voltage IS Range of IS V to 4.8 Width of the channel 20 µm Length of the (L) channel is µm conductance parameter IS 50 Linear resistance rDs is Linear resistance for equal to V is, 50 1 = = 5000 Linear resistance for equal to V is Step of Linear resistance rDs for equal to 4.8 V is, 1 50 1 = 250 Ω Linear resistance rDs for equal to 4.8V is 250 Ω Range of resistor values is 2500 to 5000 Step (a) Device width of the channel is halved and hence width of the channel is 10 µm Linear resistance for equal to V is, 1 = 50 = = 10000 Ω Linear resistance rDs for equal to V is 10000 Step of 9 Linear resistance for equal to 4.8 V is, 1 50 = 500 Linear resistance for equal to 4.8V IS 500 Range of resistor values after width of the channel is halved is to 10000 Step 9 (b) Device length of the channel is halved and hence length of the channel IS 0.5 µm Linear resistance rDs for equal to V is, I 20 1 = 2500 Ω Linear resistance for equal to Step Linear resistance for equal to 4.8 V is, 1 = 50 I = Step of 9 Linear resistance rDs for equal to 4.8V is 125 Ω Range of resistor values after length of the channel is halved is to 2500 Step of (c) Device length and width of the channel is halved and hence length of the channel is 0.5 µm width of the channel is 10 µm Linear resistance for equal to V is, I 50 = 5000 Linear resistance rDs for equal to V is Step of 9 Linear resistance for equal to 4.8 1 50 10 I = Range of resistor values after width and length of the channel are halved is 2500 to 5000
