Abstract :
This paper offers a CAD program, SIFDS (switched current filter design system), which can be used to design Butterworth, Chebyshev and elliptic types of SI filters; each type includes low-pass (LP), high pass (HP), band-pass (BP) and band-elimination (BE) filters, giving a total of 12 kinds of filters. By inputting target filter specifications, this CAD tool can yield the transfer function H(z), signal flow graph (SFG), amplitude-frequency curve and circuit structure of the filter
