Step 1 of 3 037E Refer to the Figure 12.38 in the text book. The area of transistors is directly proportional to the reverse saturation current. Refer to the equation 12.129 in the text book. Write the expression for current. Rearrange the equation to determine the resistance Substitute 25 mV for for / and 2 for = = 1732.87 Ω = 1.732 kΩ Therefore, the value of resistance is kΩ Step 2 of 3 Write the expression of voltage drop across the resistance = Substitute 0.2 V for V and for 0.2 = 20 kΩ Therefore, the value of resistance is Step 3 of 3 Write the expression of voltage drop across the resistance Substitute 0.2 V for V and 10 for = 20 Therefore, the value of resistance is 20 kΩ
