WebBJT Transistor Modeling • A model is an equivalent circuit that represents the AC characteristics of the transistor. • A model uses circuit elements that approximate the behavior of the transistor. • There are two models commonly used in small signal AC analysis of a transistor: – r. e. model – Hybrid equivalent model. The r. e ... Webthat result input resistance vary with the dc. operating point. • Hybrid model parameter are defined at an. operating point that may or may not reflect the. actual operating point of the amplifier. f Hybrid Equivalent Model. The hybrid parameters: hie, hre, hfe, hoe are developed and used to model the transistor.
