Abstract :
This work discusses the implementation of band-pass filters derived from passive ladder prototypes using switched-current techniques. The bilinear transformation is applied to a set of modified state equations derived from a conveniently modified passive prototype filter, and from the equations a switched-current circuit is derived. Two different approaches are studied and compared by simulation
