Abstract
This paper shows how switched-current filters can be derived from passive filters obtained by the unbalancing of doubly terminated LC lattice structures. The process is similar to what would be done for the simulation of more conventional ladder structures, but the use of lattice prototypes allows the realization in an almost physically symmetrical structure. A comparation of sensitivity characteristics between second-generation and component-simulation switched-current filters is also shown
