ACTIVE FILTERING
Figure 67:
Low-Pass Active Filtering. Sallen-Key
The resistors R
fb
and R
G
give the gain of the filter
as a classical non-inverting amplification configu-
ration :
Assume the following expression is the response
of the system:
the cut-off frequency is not gain-dependent and it
becomes:
The damping factor becomes:
1
2
ω
cC1R1
The higher the gain, the more sensitive the damp-
ing factor is. When the gain is higher than 1 it is
preferable to use very stable resistors and capac-
itances values.
In the case of R1=R2:
INCREASING THE LINE LEVEL BY USING AN
ACTIVE IMPEDANCE MATCHING
With passive matching, the output signal ampli-
tude of the driver must be twice the amplitude on
the load. To go beyond this limitation, active
matching impedance can be used. With this tech-
nique, it is possible to keep good impedance
matching with an amplitude on the load higher
than half of the output driver amplitude. This con-
cept is shown in Figure 68 for a differential line.
