INCREASING THE LINE LEVEL BY USING AN
ACTIVE IMPEDANCE MATCHING
With a passive matching, the output signal ampli-
tude of the driver must be twice the amplitude on
the load. To go beyond this limitation an active
matching impedance can be used. With this tech-
nique, it is possible to keep a good impedance
matching with an amplitude on the load higher
than the half of the output driver amplitude. This
concept is shown in figure 74 for a differential line.

an active impedance matching
Component Calculation
Let us consider the equivalent circuit for a single
ended configuration, Figure75.
Figure 75 :
Single ended equivalent circuit
Let us consider the unloaded system. Assuming
the currents through R1, R2 and R3
as respectively:
As Vo
°
equals Vo without load, the gain in this
case becomes :
The gain, for the loaded system will be (eq1):
As shown in figure76, this system is an ideal gen-
erator with a synthesized impedance as the inter-
nal impedance of the system. From this, the out-
put voltage becomes:
with Ro the synthesized impedance and Iout the
output current. On the other hand Vo can be ex-
pressed as:
By identification of both equations (eq2) and
(eq3), the synthesized impedance is, with
Rs1=Rs2=Rs:
