8 Active Filtering
From the resistors R
fb
and R
G
we can directly calculate the gain of the filter in a classical non-inverting
amplification configuration:
We assume the following expression as the response of the system:
The cut-off frequency is not gain-dependent and so becomes:
The damping factor is calculated by the following expression:
The higher the gain, the more sensitive the damping factor is. When the gain is higher than 1, it is
preferable to use some very stable resistor and capacitor values. In the case of R1=R2=R:
Due to a limited selection of values of capacitors in comparison with resistors, we can fix C1=C2=C, so
that:
