Jul 1, 2011 · The hybrid-pi model is a popular circuit model used for analyzing the small-signal behavior of transistors. The hybrid-pi models apply only to devices in active mode; that is, the DC biases are applied to set the operating point or Q-point in the normal operating regime for analog circuit operation. [1] shows the hybrid - ∏ model for a transistor in CE configuration. For this model in figure 4.2.3, all parameters are assumed to be independent of frequency. But they may vary with the quiescent operating point.
