Original Abstract

In this paper the current-mode low- and high-pass filters employing current conveyors as active elements are presented, whereas the proposed solutions are suitable for the approximation of fractional-order transfer function of the order (1+α), for 0 < α < 1. The advantageous features of the proposed solutions is the usage of minimal number of passive elements, whereas all are grounded, and ideally zero-input and infinite-output impedance. Based on the theoretical behavior description, the performance of the proposed circuits was verified by means of Spice simulations using macro models of the UCC-N1B integrated circuit.

Czech abstract

V článku jsou prezentovány kmitočtové filtry typu dolní a horní propusti s proudovými konvejory jako aktivními prvky pracující v proudovém režimu, kdy popsané obvody jsou vhodné pro aproximaci fraktální přenosové funkce řádu (1+\alpha), pro 0 < \alpha < 1. Výhodnými vlastnostmi navržených řešení je použití minimálního počtu pasivních prvků, přičemž všechny jsou uzeměny, a teoreticky nulová vstupní a nekonečný výstupní impedance. Na základě teoretického popisu bylo chování obvodů ověřeno simulacemi ve Spice použitím makromodelu integrovaného obvodu UCC-N1B.
