Step of 6 8.001P Refer to Figure 8.1 from the text book. Consider the expression for the output current. Substitute 100 for 500 for 0.5 um for L 5 for W and 0.4 V for 100 2 = 2 Step of 6 Solve for the value of Or The value of should be less greater than the value of for the transistor to operate in saturation region. Hence, the required value of GS is 0.6 Step of 6 Consider the expression for the drain current Substitute 100 for 1.3 V for and 0.6 V for 100 1.3-0.6 R 100 0.7 R Solve for the value of R R 0.7 100 Therefore, the value of the resistor R is Step of 6 The value of the output voltage will be minimum when Hence, calculate the value of the output voltage. Substitute 0.6 V for and 0.4 V for = 0.2 V Therefore, the minimum value of the output voltage is 0.2 V V Step of 6 Consider the expression for the output resistance of the current source Substitute 100 for 0.5 for L and 5 V/µA for = 100 = 2.5 100 Therefore, the value of the output resistance of the current source is Step of 6 Consider the expression for the output resistance of the current source in terms of change in output voltage to change in output current. Substitute 0.5 V for and 25 kΩ for 25k=0.5 Solve for the value of 0.5 25k k =20 Therefore, the value of the change in output current is 20
