Original Abstract

A multifunctional filter with Digitally Adjustable Current Amplifier (DACA), two balanced transconductance amplifiers (OTAs) and two passive elements is presented in this paper. The natural frequency of the filter is tunable, quality factor is adjustable, filter is of the single-input multiple-output (SIMO) type, and operates in the current mode. The contribution contains simulation results that were obtained with the help of behavioral model of the UCC-N1B 0520, UVC-N1B 0520 and EL2082 elements and also measurement results. The presented simulation results prove the quality of designed filter.

Multifunkční filtr s digitálně řiditelným proudovým zesilovačem (DACA), dvěma transkonduktančními zesilovači (OTA) se symetrickými výstupy a dvěma pasivními prvky je prezentován v tomto článku. Úhlový kmitočet filtru je přeladitelný, činitel jakosti je nastavitelný. Filtr je typu jeden vstup - více výstupů (SIMO) a pracuje v proudovém módu. Příspěvek obsahuje výsledky simulací, které byly obdrženy s pomocí behaviorálního modelu prvku UCC-N1B 0520 a prvku EL2082, výsledky měření jsou rovněž zahrnuty. Prezentované výsledky potvrzují kvalitu navrženého filtru.
