Increasing the line level using active impedance matching

Increasing the line level using active impedance

matching

With passive matching, the output signal amplitude 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 technique, it is possible to maintain good impedance matching with an amplitude on the

load higher than half of the output driver amplitude. This concept is shown in Figure 68 for a

differential line.

Let us consider the equivalent circuit for a single-ended configuration, as shown in

Figure 69.
