Hi all,
A model of common-emitter transconductance stage is shown as Transistor_Equivalent_Circuit.jpg.
Who can tell me what Cb is? Some paper describe Cb as base-charging capacitor, and it is linearly proportional to the collector current Ic and the forward transit time(TF) of transistor. Could you explain this problem for me in detail and what the forward transir time is?
Thanks!
