WebSmall-Signal Models There are two small-signal circuit models which are commonly used to analyze MOSFET circuits. These are the hybrid-πmodel and the T model. The two models are equivalent and give identical results. They are described below. Hybrid-πModel Let the drain current and each voltage be written as the sum of a dc component and a ...

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.
