Abstract :
Fully differential solutions for switched-current filters are described. The proposed circuits, besides reducing the clock feedthrough effect, improve the linearity of equivalent single-ended solutions and offer additional degrees of freedom. Some basic building blocks required in switched-current filters (like integrators and derivators) are realized in the fully differential approach
