hi,
could someone provide guidance or idea for a start?
the question is to find an expression for β cutoff frequency Fb which is simply a high freq current gain cutoff point of the transistor with collector & emitter terminals shorted as seen in the attached.
is the expression Fb= 1/2\(\pi\)r(C\(_{}\pi\) + C\(_{}\mu\))
is that correct?
thanks
