Need to design and construct a two-stage amplifier with a total voltage gain of A = A1 ∙ A2 = -Z where Z is 35. Let A1 be the gain of the first amplifier and A2 be the gain of the second amplifier. The output of Stage 1 becomes the input of Stage 2. Choose any suitable values |A|1 > 1 and |A2| >1 that you wish (Note that both gains must be strictly larger than 1. No buffers). Assume...
