What would be the output voltage amplitude be if you used 1

Question

Include step by step answer in details.

1. You have a source which outputs a signal with a 5-mV amplitude. The source output resistance is 10 KΩ (R_s = 10 kΩ). You want to amplify this signal and deliver it to a 1-KΩ load (R_L = 1kΩ). To do the amplification, you have a large number of identical amplifier cΩponents. The amplifiers have open-loop gain of 5 (A= 5), input resistance of 10 kΩ (R_i= 10 k Ω), and output resistance of 1 kΩ  (R_o = 1 kΩ).

• What would be the output voltage amplitude be if you used 1 amplifier stage?

V_out1=

• What would be the output voltage amplitude be if you cascaded 2 amplifier stages between the source and the load?

V_out2=

• Three stages?
V_out3=

• n stages? (This answer should be an expression that involves n.)
v_outn=

• If you use a different type of amplifier which has R_i = 100 kΩ, R_o = 0.1 kΩ, and A = 10, how many stages would be required to have the output signal amplitude be at least 2.0 V?
