Acm. Dequeiroz et Pm. Pinheiro, BILINEAR SWITCHED-CURRENT LADDER FILTERS USING EULER INTEGRATORS, IEEE transactions on circuits and systems. 2, Analog and digital signal processing, 43(1), 1996, pp. 66-70
This brief discusses the implementation of exact simulations of passiv
e filters by switched-current techniques, using the bilinear transform
ation, but avoiding the use of true bilinear integrators. It is shown
that the synthesis can be easily done directly using switched-current
Euler integrators, without passing through an intermediary switched-ca
pacitor filter. The method is exemplified for low-pass filters built w
ith ''second-generation'' Euler integrators.
