transistors with active inductance
Figure 7. Theoretical and experimental dependence of the active component
of the impedance of the supply voltage
Figure 8 shows the theoretical and experimental dependence of the reactive
component of the impedance from the supply voltage. As it is seen from the graph that
with increasing U

from 8.5 V to 12.5 V (

U
= 4V), the reactive component increases
to a greater extent than from 12.5 V to 14 V.
