APPLICATION NOTE 1762
A Beginner's Guide to Filter Topologies


Abstract:This article is an excellent introduction to analog filters. It covers the basic first and second order filter types as well as
the advantages and disadvantages of passive and active filters. It derives and analyzes the basic biquad implementation using
several op amp implementation examples.

The world of filter design is often thought of as black magic because of the myriad of configurations, unique terminology, and
complex equations. This application note will look at different filter types, shed some light on termino……
