8.6.8.2 Output Characteristics (C.E.)
The output characteristics of a BJT in C.E. conguration show the (output) I
C
cur-
rent as a function of the (output) voltage V
CE
parameterized to (input) I
B
current,
as in Figure 8.50.
In the rst part the curves are quite linear, with a low resistive value (when V
CE
is low, typically ≤0.2 V), after that a short transition curve, and then a rather high
resistive linear behavior. We have a transition from an initial situation of low resis-
tance to a nal one of high resistance.
Curiosity
The term “transistor” comes from the very fact the device conducts a sort of transf ...
