9-POLE CHEBYCHEV FILTER
Figure 50 and Figure 51 show the AD712 and its dual counterpart,
the AD711, as a 9-pole Chebychev filter using active frequency
dependent negative resistors (FDNRs). With a cutoff frequency
of 50 kHz and better than 90 dB rejection, it can be used as an
antialiasing filter for a 12-bit data acquisition system with
100 kHz throughput.
As shown in Figure 50, the filter is comprised of four FDNRs
(A, B, C, D) having values of 4.9395 × 10
farad-seconds. Each FDNR active network provides a two-pole
response for eight poles. The ninth pole consists of a 0.001 μF
capacitor and a 124 kΩ resistor at Pin 3 of Amplifier A2. Figure 51
depicts the circuits for each FDNR with the proper selection of
R. To achieve optimal performance, the 0.001 μF capacitors
must be selected for 1% or better matching and all resistors
should have 1% or better tolerance.
