cascode amplifier small signal equivalent circuit
I've been trying to find the small signal equivalent model for the cascode BJT amplifier circuit below, however I don't think I am getting the right model, I can find the model for one transistor, but don't know how to find it for cascode transistors.
Anyone can tell me how the small signal model for this circuit should look like ?
Thanks in advance ^-^
