9-POLE CHEBYCHEV FILTER
Figure 17 shows the AD711 and its dual counterpart, the AD712,
as a 9-pole Chebychev filter using active frequency dependent
negative resistors (FDNR). With a cutoff frequency of 50 kHz
and better than 90 dB rejection, it may be used as an anti-aliasing
filter for a 12-bit data acquisition system with 100 kHz throughput.
As shown in Figure 17, the filter is comprised of four FDNRs (A,
B, C, D) having values of 4.9395
10
–15 and 5.9276
10
–15 farad-seconds. Each FDNR active network provides a
2-pole response; for a total of 8 poles. The 9th pole consists of a
0.001
mF capacitor and a 124 kW resistor at Pin 3 of amplifier A2.
Figure 18 depicts the circuits for each FDNR with the proper
selection of R. To achieve optimal performance, the 0.001
mF
capacitors must be selected for 1% or better matching and all
resistors should have 1% or better tolerance.
