Step 1 of 3 8.031E Refer to Figure 7.41 in the circuit for the amplifier circuits. Analysis of both the circuits is illustrated in Figure 7.42 in the text book. Both the circuits have the same input resistance and the same voltage gain. Determine the resistance, = = Determine the input resistance, = + Substitute 100 for and 25 Ω Ω for = = 5050 Ω = 5.05 kΩ Step 2 of 3 Determine α₂ = 100 = 100+1 =0.99 1 Determine the ratio, = v, Substitute 1 for Ω for and 25 Ω Ω for r. r. = 2x25 Thus, the voltage gain is 100 V/V Step 3 of 3 Determine the ratio, Substitute Ω for 5x Ω for and 100 V/V for Thus, the gain is 50 V/V - Vsig
