Two transformation methods for obtaining new topologies from a given current-mode CCII filter are presented. These topologies realise the same transfer function as the initial filler for ideal CCIIs, but they can be derived in such a way that their active sensitivity with respect to a particular active parameter becomes zero. In this way, from a filter suffering from large active sensitivities, one may systematically obtain new filters with better active sensitivities.
