Step of 7 8.002P Refer to Figure 8.1 from the text book. Consider the expression for the value of Substitute 0.3 V for and 0.5 V for 0.8 V Therefore, the value of the voltage is, 0.8 V Step of 7 Consider the expression for the drain current, R Substitute 150 for 1.8 V for and 0.8 V for 1.8-0.8 150 R 1 150 = R Solve for the value of R 1 R 160 Therefore, the value of the resistor R is, Step Calculate the value of the change in the output current, Substitute 150 for Therefore, the value of the change in output current is, 15 Step of 7 Calculate the value of the change in output voltage, Substitute 1.8 V for and 0.3 V for =1.5 V Therefore, the value of the output voltage is, 1.5 V Step of Consider the expression for the output resistance of the current source, in terms of change in output voltage to change in output Substitute 1.5 V for and 15 for 1.5 = 100 Therefore, the value of the output resistance is, 100 Step of Consider the expression for the output resistance of the current source in terms of early effect and drain current. Substitute 150 for 100 for and 10 V/µA for 100 Solve for the value of L L 1.5 Therefore, the value of the length L of the device is, 1.5 Step of 7 Consider the expression for the output current, Substitute 150 for 400 for 1.5 µm for L 0.8 V for and 0.5 V for V, Solve for the value of W W W 450 W W 12.5 um Therefore, the value of width of the device W is, 12.5
