Step of 7 8.012P Refer to Figure P8.12 from the text book. Consider the expression for the output current. 2 Assume 0.7 V for Substitute 50 for for and 50 for 50 2 50 1.3 50 50 50+1.3 50 50+2 50 = 52 1 (0.987) REF 0.987 REF 1.014 mA Therefore, the value of the reference current REF is 1.014 mA Step of 7 Calculate the value of the collector voltage Vc Assume 0.7 V for Substitute for Therefore, the value of the collector voltage Vc is V Step of 7 Calculate the value of the resistance R REF Substitute 2.3 V for Vc and 1.014 mA for REF R 2.3 1.014 m Therefore, the value of the resistance R is, Step of 7 Calculate the value of the output resistance Substitute 50 V for and mA for 50 Therefore, the value of the output resistance is, Step of The maximum value of the output voltage occurs for the minimum value of the emitter to collector voltage, that is for the value of 0.3 V Hence, calculate the value of the maximum value of the output voltage. Substitute 3 V for and 0.3 V for =3-0.3 Therefore, the maximum value of the output voltage is Step 7 Consider the expression for the value of the output resistance in terms of the change in output voltage and the change in the output current. Substitute 50 kΩ and 50 2.7-(-5) 50 2.7+5 7.7 0.154 mA Therefore, the value of the change in current is, 0.154 mA Step of 7 Calculate the percentage change in the value of output current. Substitute 0.154 mA for and 1 mA for 0.154 =0.154x100 =15.4% Therefore, he value of the percentage change in the output current is, 15.4%
