Abstract

A method is introduced for designing stable, active integrated ladder filters with canonic numbers of op amps from a class of hitherto problematic transfer functions including bandstop and even-order elliptic functions. A variety of familiar parasitic-insensitive ladder structures can be produced by matrix methods while retaining the low sensitivity properties expected of passive simulations. The method is applicable to active-RC, switched-capacitor, and digital technologies
