WebSep 6, 2024 · AC Analysis is used to calculate the small-signal response of a circuit. In AC Analysis, the DC operating point is first calculated to obtain linear, small-signal models for all nonlinear components. Then, the equivalent circuit is analyzed from a start to a stop frequency. The result of an AC Analysis is displayed in two parts: gain versus ... WebSep 9, 2024 · The other reason to use a small-signal model is to avoid the need to consider harmonics generated for AC signals. Mathematically, the current/voltage relationship in a nonlinear component can be approximated using a Taylor or Maclaurin series, which gives a high degree polynomial. For an AC signal, taking powers of the input voltage will ...
