This project is intended to provide a useful design tool for switched capacitor filters. The aim is to calculate the best implementation (with the smallest space needed) for such a filter. It will further be a tool for general filter design later.

The following SC circuit types have been added: - 2nd order filter with multiple feedback The following computation types are available: - Bilinear (or Tustin's) method - Euler with exact representation of negative resistances in biquad sections. - Euler with delayed representation of negative resistances in biquad sections.

Hi everybody, A new version is available after long time of waiting. Fortunately I was able to proove lots of concepts used in the previous and new version by means of ICs I actually designed and measured. The new version includes the revised computation formulas for the different approximation methods that are feasible with SC circuits. Still, I need your help regarding the modeling of other SC circuit variants, synthesizing filters and so on. Best regards, Uwe Mayer
