Amplifier Matching Examples
The Amplifier Matching Problem is a problem of multiobjective trade-offs. As Figure 6.1 illustrates, the goal is to amplify the input signal S i to a larger output signal S 0 , not to amplify the input noise V i to a much larger output noise N 0 , and not to have the entire circuit become unstable and blow up. To achieve these three competing objectives, the amplifier designer optimizes over classes of input and output matching circuits to simultaneously tradeoff

AMP-2 Minimizing the noise figure F.
AMP-3 Guaranteeing stability: |S 1|≤,|S 2|.
