Step of 8 11.008E Refer to the Figure E10.11 in the text book. The emitter current of transistors and is, Determine the value of emitter resistors of transistors and 25mV 0.5mA Determine the value of emitter resistors of transistor 25mV 5mA =5Ω Step 8 Determine the value of gain of the feedback amplifier. A= A R, B+1 Substitute for 100 for 2kQ for 1kQ for 9kQ for R2 for and for 5Ω for and for R, A= A 10x10 50+50+ 100+1 100+1 = 50+50+99+8.9 = (0.997) 207.9 =85.9 V/V Therefore, the gain of the amplifier is 85.9 V/V Step Determine the value of feedback factor. Substitute 1kQ for and 9kQ for R2 10 =0.1 V/V Therefore, the value of feedback factor of the amplifier is 0.1 V/V Step of 8 Determine the voltage gain feedback amplifier. A Substitute 85.9 V/V for A and 0.1 for 85.9 1+(85.9)(0.1) 85.9 1+8.59 =8.96 V/V Thus, the voltage gain of the amplifier with feedback is 8.96 V/V Step Determine the value of input impedance without feedback Substitute for R, 100 for for and for 1kQ for and 9kQ for R2 Step of Determine the input resistance of the feedback amplifier. Substitute for 85.9 0.1for and 10kQ for =191kQ Therefore, the value of input resistance of the feedback amplifier is Step of 8 Determine the output resistance amplifier without Substitute for 100 for 2kQ for 1kQ for and 9kQ for R2 100+1 =181Ω Step of 8 Determine the output resistance of the feedback amplifier. Substitute for 85.9 for A, 1for and 2kQ for 181 1+(85.9)(0.1) Therefore, the value of output resistance of the feedback amplifier is 8.87
