Chapter 10: Multi stage amplifier configurations
It is necessary to consider what happens when non-ideal amplifiers are put in series. Looking at the example in figure 10.1, it is clear that the input and output resistances (or impedances) come into play by reducing the overall gain. If the amplifiers were ideal (R out = 0 and R in = ∞), and amplifier stages #1 and #2 had gains of A 1 and A 2, the overall …
