I have a question about the nodal equations of BJTs - when analyzing a circuit to find out the input impedance, output impedance etc. is the term representing the intrinsic emitter resistance, Rbe (that is approximately 26mv/Ic) multiplied by the term beta+1? I'm looking at two references, and in one of them the output impedance of an emitter follower is calculated with the intrinsic emitter resistance and the external resistor both multiplied by beta+1, and another just has the external emitter resistance multiplied by beta+1 and not Rbe.(adsbygoogle = window.adsbygoogle || []).push({});
