WebNov 29, 2024 · The aim of any small signal amplifier is to amplify all of the input signal with the minimum amount of distortion possible to the output signal, in other words, the output signal must be an exact reproduction of the input signal but only bigger (amplified). WebOct 24, 2024 · Figure 1: Simplified op amp small-signal model. If op amp manufacturers do not model Zo accurately, then the overall small-signal AC behavior of an op amp model is incorrect and can’t be used for stability analysis. Thankfully, it’s easy to verify that a model’s Zo matches the data sheet. Figure 2 shows the recommended test circuit.
