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. WebSmall-signal modeling is a common analysis technique in electronics engineering used to approximate the behavior of electronic circuits containing nonlinear devices with linear equations.It is applicable to electronic circuits in which the AC signals (i.e., the time-varying currents and voltages in the circuit) are small relative to the DC bias currents and voltages.
