Steady-state stage-wise circuit analysis
Doc ID 018840 Rev 1
23/78
System of equations 6
where ICBp and VCBp are, respectively, the current and voltage signal of the forward biased
C-B junction diode of the PNP bipolar. During this phase, in general, VEBp(t) is so that
0<VEBp(t)<VEBp-on for the PNP bipolar E-B junction diode but if it were VEBp(t)<0 the device
would work in reverse active region since it is VCBp(t)>0. Therefore, in this last case,
currents and voltages on the driving network are depicted by the information in Figure 14.
