"WebApr 5, 2024 · If you are running an .AC analysis, which is a "small signal" linear simulation, LTspice first finds the operating point, then it linearizes the nonlinear model by considering the values and slopes of its nonlinear equations at that operating point. Thus, the simulation is "small-signal" linear, but it uses the large-signal nonlinear MOSFET model. " - Small signal analysis mosfet
