Universal fully-differential adjustable filter with current conveyors and current amplifier in comparison with single-ended solution

Jan Jeřábek, Kamil Vrba, Mojmir Jelinek

Abstract

Novel fully-differential (F-D) adjustable filter with three fully-differential current conveyors (FD-CCII) and one digitally adjustable current conveyor (DACA) is presented in this contribution. Structure is universal because each of the five standard functions is provided. Comparison with initial single-ended (S-E) solution with three universal current conveyors (UCC) and one DACA is provided. Simulations were performed with 3rd order models that are also included.
