In this paper we introduce a tool for symbolic analysis and design of analog
active filters. It has been developed in Mathematica.
The tool can be used to draw circuit schematics, and to formulate and
solve analysis and design equations.
We present a closed-form solution for a design problem that would
otherwise only be possible by numerical optimization or trial-and-error
guessing and simulation.
Illustrative examples are given to demonstrate filter design with
minimization of the sensitivity, and optimization of element values
to have prescribed values.
