Web5.6.1. Small signal model (hybrid pi model) The hybrid pi model of a BJT is a small signal model, named after the “π”-like equivalent circuit for a bipolar junction transistor. The model is shown in Figure 5.6.1. It consists of an input impedance, rπ, an output WebHigh frequency effects on BJT. The gain decreases at high frequencies due to internal feedback capacitance’s.The highest frequency of operation of BJT will be limited by internal capacitance’s of BJT. The on and off switching times of BJT will be high and speed will be limited due to internal charge storage effects. High frequency model of BJT.
