Original Abstract

A voltage-mode high input impedance differential input-differential output second-order band-reject filter based on two differential difference current conveyors (DDCCs) and one second-generation current conveyor (CCII) is presented. The proposed structure features high input impedance, a minimum number of passive elements – all being grounded, high common-mode rejection ratio, and low sensitivity. The tracking error and sensitivity analysis of the proposed circuit are given. The performance of the filter structure is verified by simulations and also experimentally measured using the UCC-N1B integrated circuit.

Czech abstract

V článku je prezentována pásmová zádrž druhého řádu s diferenčním vstupem a diferenčním výstupem s vysokou vstupní impledancí pracující v napěťovém módu. Jako aktivní prvky jsou použity dva DDCC (differential difference current conveyors) a jeden CCII (second-generation current conveyor). Řešení se vykazuje vysokou vstupní impedancí, minimálním počtem pasivních prvků (všechny jsou uzeměny), vysokým potlačením souhlasného signálu a malou citlivostí. Je analyzován vliv chyby aktivních prvků a citlivostní analýza. Chování filtru je ověřeno simulaceni a také experimentálním měřením využitím integrovaného obvodu UCC-N1B.
