Low-frequency small-signal model equivalent circuit of triode

DFN1006 TP-RCLAMP3321P ESD Diode Low Capacitance

The following is a circuit diagram of [Equivalent Circuit of Low-Frequency Small Signal Model of Transistor ]

Model establishment
1. A triode can be replaced with a model.
2. The effect of junction capacitance can be ignored for low frequency models.
3. Small signals mean that the triode works under linear conditions, and the micro-variation also has the same meaning as linear.
The low frequency small signal model of the triode is shown in the figure.
