APPLICATION NOTE 727
Filter Design Using Integrator Blocks


Abstract:This application note explains a method that uses integrator blocks and some simple mathematical manipulation to
produce filter responses of any order. The method is precise, easy to apply, and an alternative to a "standard" set of filter
networks when a nonstandard filter response is needed.


Introduction
Much literature and software has been published on the design and implementation of standard filter responses. When a
nonstandard filter response is required, it is often left to the circuit designer to produce a solution using his or her o
