Ladder based transconductor-capacitor filter and equaliser design

Describes a topological matrix decomposition method for ladder based transconductor-C filter design and for an equally terminated ladder prototype filter this gives a realisation in which all the transconductance values are identical. Both conventional and low-impedance input transconductor sections can be utilised in filter and equaliser design. Fewer transconductors are required by the topological decomposition method than by the other ladder based transconductor-capacitor design techniques. The low sensitivity properties common to all the ladder based methods are preserved and comparative sensitivity studies including cascade biquad circuits are shown. The problem of realising such ladder based structures with a canonic number of transconductors is addressed
