Hi All,
I have the following circuit
and I want to calculate the resistances seen by the parasitic capacitances of the bjt (\(C_{\pi}\) is the capacitance between emitter and base, while \(C_{\mu}\) is the capacitance between base and collector). I can ignore Early effect. I think that \(R^0_{\pi} = 0\), since the output impedance of the ideal op. amp. is infinite. About \(R^0_{\mu}\), I can say that the short circuit between base and collector implies \(R^0_{\mu} = 0\) too.
Could you help me ?
Thank you!
