NETTAN -A tool for Analysis and Iterative Design of Analog-, Digital-and Switched-Capacitor Filters

NETTAN is a versatile development platform for filter analysis and design. It contains analysis algorithms for filters enabling the user to characterise a given filter or iteratively synthesise a filter for a target specification by optimisation. Filters included are passive RLC-, active RC-, digital and switched-capacitor filters. The platform, written in the Fortran language, is free software released with the Gnu General Public License (GPL) version 3 or later. It is especially useful for all parties interested to contribute with new analysis and/or synthesis methods. Other uses are for educational purposes, and NETTAN can be included in any graduate course having filters as one of the course subjects. Usage of the tool is simplified by the users manual and an on-line help.
