Script for Maxima (a Computer Algebra System) that performs symbolic analysis of analog integrated circuits. Script allows to find approximated poles and zeros of transfer functions, developed and optimized for transfer functions of amplifiers, but can be used also for any general analog circuit. The script calculates DC transfer function, zeros, poles and creates Bode plots. DC transfer function, zeros, poles result simplified so main contributing elements can be easily identified.
Poles and zeros approximation principle mainly taken from the paper "INDIRECT FEEDBACK COMPENSATION TECHNIQUES FOR MULTI-STAGE OPERATIONAL AMPLIFIERS" by Vishal Saxena
Usage examples also can be taken from "Maxima Opamp Analisys" project
Any comments bug reports and improvement suggestions are welcomed!
** The project based on script and concept initially developed by Ram Livne **
