Abstract :
The authors describe SINFILAT, a computer program that performs the synthesis of active filters consisting of optimized cascaded second-order sections. The features include pole and zero pairing, section ordering, optimized section synthesis, predistortion, impedance scaling, automatic active compensation, and designed circuit diagrams. In order to illustrate the use of SINFILAT, a bandpass elliptic filter with 1 dB passband ripple and 42 dB stopband attenuation was designed
