At the frequency of interest, a BJT transistor is represented by an equivalent model with only the junction capacitor [C.sub.[pi]] [approximate] 2[C.sub.jeo] + [g.sub.m][tau]F and the base resistance [r.sub.[pi]] taken into account in the input port, where [C.sub.jeo] is the junction capacitance between base and emitter at zero bias, [g.sub.m] is the transconductance and [[tau].sub.F] is the forward base transit time.
The differences between the models of Tin [9] and Lee [10] are the explicit substrate junction capacitors, [C.sub.jdb] and [C.sub.jsb].
